CBSE Class 12 Chemistry 2026-27: Organic, Inorganic and Physical — Complete Guide
Class 12 chemistry is really three subjects in one paper. Physical chemistry is numerical and formula-driven. Inorganic chemistry is about trends, electronic configurations and reasons. Organic chemistry is about reactions, mechanisms and conversions. Most students are comfortable with one or two of these and quietly avoid the third. That is where marks go missing, because the 2026-27 paper draws on all ten chapters and gives no chapter-wise choice.
This guide is written for the 2026-27 batch, who sit the board exam in 2027. It covers the official chapter-wise weightage, the question paper design, the chapters that are now assessed only formatively, the practical exam, a chapter-by-chapter guide to all ten NCERT chapters with the key reactions and results, a month-by-month plan, a last-30-days checklist, common mistakes, and how to balance the board paper with NEET, JEE and CUET. The syllabus and paper details have been checked against CBSE's 2026-27 curriculum and sample question paper.
CBSE Class 12 Chemistry 2026-27 at a glance
Subject code – Chemistry (043).
Marks – 70 for the theory paper and 30 for the practical exam, 100 in total.
Paper – 3 hours, 33 compulsory questions in five sections (A to E), with internal choice in some questions.
Syllabus – ten chapters from NCERT Chemistry Part I and Part II for Class 12.
No calculators or log tables – the sample paper states that neither is allowed, so numericals are set with manageable numbers.
No change – CBSE's 2026-27 sample paper states there is no change in the question paper design and assessment pattern for this session.
Class 12 has one main board exam; the two-exam system introduced from 2026 applies to Class 10. In 2026, Class 12 practical exams began in January and theory exams began on 17 February. The 2027 date sheet has not yet been published, so take exact dates from cbse.gov.in when they are announced.
Syllabus and chapter-wise weightage
Unlike maths and physics, the chemistry curriculum gives marks chapter by chapter. We have grouped the chapters by branch to show the balance:
| Branch | Chapter (NCERT) | Marks (out of 70) |
|---|---|---|
| Physical | 1. Solutions | 7 |
| Physical | 2. Electrochemistry | 9 |
| Physical | 3. Chemical Kinetics | 7 |
| Inorganic | 4. The d- and f-Block Elements | 7 |
| Inorganic | 5. Coordination Compounds | 7 |
| Organic | 6. Haloalkanes and Haloarenes | 6 |
| Organic | 7. Alcohols, Phenols and Ethers | 6 |
| Organic | 8. Aldehydes, Ketones and Carboxylic Acids | 8 |
| Organic | 9. Amines | 6 |
| Organic | 10. Biomolecules | 7 |
| Total theory | 10 chapters | 70 |
| Practical | Volumetric, salt analysis, experiment, project, record and viva | 30 |
Adding up by branch: physical chemistry carries 23 marks, inorganic chemistry 14 marks, and organic chemistry 33 marks. Organic is nearly half the paper, so it cannot be left to the end. Electrochemistry (9) and Aldehydes, Ketones and Carboxylic Acids (8) are the two heaviest single chapters. The question paper design adds that care must be taken to cover all chapters.
What is formative-only or no longer in the Class 12 syllabus
This is the section older guides get most wrong, including an earlier version of this post. The Class 12 chemistry syllabus has changed a great deal in recent years.
Assessed only formatively in 2026-27
The 2026-27 curriculum lists four topics that are "included in the syllabus but will be assessed only formatively to reinforce understanding without adding to summative assessments". CBSE provides the relevant NCERT reading material separately. These will not be tested in the board theory paper:
- Surface Chemistry: adsorption (physisorption and chemisorption), factors affecting adsorption of gases on solids, the colloidal state, lyophilic and lyophobic colloids, coagulation and types of emulsions.
- General Principles and Processes of Isolation of Elements: concentration, oxidation, reduction, electrolytic method and refining.
- Polymers: polymerisation, homopolymers and copolymers with a few examples.
- Chemistry in Everyday Life: chemicals in medicines (analgesics, tranquilisers, antiseptics, disinfectants, antimicrobials, antifertility drugs, antibiotics, antacids, antihistamines) and chemicals in food (preservatives, artificial sweeteners, antioxidants).
Your school may still teach these and test them in class. Surface chemistry also appears in the practical syllabus (preparing sols, dialysis, emulsions), so do not ignore it for the lab.
Not in the Class 12 syllabus at all
- The p-Block Elements (Groups 15 to 18) are not part of the current Class 12 syllabus. Older guides that call p-block "high priority" for the board are out of date.
- The Solid State is not in the current Class 12 syllabus.
- Environmental Chemistry is not a Class 12 chapter.
- General organic chemistry (hybridisation, inductive effect, resonance, nomenclature basics) is a Class 11 chapter. You need it as a foundation for every organic chapter, but it is not a separate Class 12 chapter.
Some of these topics remain important for entrance exams. That is covered in the section on NEET, JEE and CUET below.
Question paper design for 2027
This structure is taken from CBSE's 2026-27 Chemistry sample question paper:
| Section | Questions | Type | Marks each | Section total |
|---|---|---|---|---|
| A | 1–16 | MCQs, including 4 assertion–reason | 1 | 16 |
| B | 17–21 | Very short answer | 2 | 10 |
| C | 22–28 | Short answer | 3 | 21 |
| D | 29–30 | Case-based or data-based | 4 | 8 |
| E | 31–33 | Long answer | 5 | 15 |
| Total | 33 | 70 |
There is no overall choice. The curriculum says 33% internal choice is given across all sections; in the sample paper, choices appear in Section B, Section C, the 2-mark parts of both case studies, and all three long answers.
The thinking skills the paper tests
| Type of question | Marks | Share |
|---|---|---|
| Remembering and understanding | 28 | 40% |
| Applying | 21 | 30% |
| Analysing, evaluating and creating | 21 | 30% |
Sixty per cent of the paper rewards applying and reasoning, not recall. The 2026-27 sample paper shows what this means: a table of boiling points and pKb values for three amines, a log k versus 1/T plot to read the activation energy from, a graph of pKa values of substituted phenols, experimental cell EMF values to compare with the Nernst equation, and a student's Benedict's-test observations to identify a carbohydrate. You need the reactions, but you also need to read data.
How to handle each question type
MCQs – Many test one reaction or one trend. Eliminate options that contradict a known fact; the rest usually becomes clear.
Assertion–reason – Judge each statement separately. In the sample paper, the claim that nitration of aniline gives significant meta product is true, and the reason that –NH₂ is ortho/para directing is also true, but it does not explain the assertion.
2-mark questions – Balanced equations, a short reason, or two one-mark parts. Be precise; one missing reagent can cost half the marks.
3-mark questions – Short numericals (activation energy, colligative properties), name reactions with missing reactants or products, and two-step conversions.
Case-based questions – Read the data or graph carefully; two 1-mark parts and a 2-mark part with choice.
5-mark questions – Often five 1-mark reasoning parts on one chapter (coordination compounds in the sample paper) or a mix of a numerical and reasoning.
Practical exam: 30 marks
| Component | Marks |
|---|---|
| Volumetric analysis | 8 |
| Salt analysis | 8 |
| Content-based experiment | 6 |
| Project work | 4 |
| Class record and viva | 4 |
| Total | 30 |
Volumetric analysis in the 2026-27 syllabus is the titration of KMnO₄ against a standard solution of oxalic acid or ferrous ammonium sulphate (Mohr's salt), with students preparing the standard solution by weighing it themselves. Salt analysis is the identification of one cation and one anion in a given salt; insoluble salts are excluded. Content-based experiments come from areas such as surface chemistry (sols), chemical kinetics (sodium thiosulphate with HCl), thermochemistry, the Zn/Cu cell, chromatography, preparation of inorganic and organic compounds, functional group tests, and tests for carbohydrates, fats and proteins.
Practise titrations until concordant readings come quickly.
Learn the salt-analysis flow chart and the confirmatory test for each ion.
Know the chemistry behind each functional group test, not only the colour.
Keep the record complete and signed through the year.
Choose a project you actually carry out; the viva will ask about it.
Chapter-by-chapter guide to all ten chapters
For each chapter: what the board tests, the key reactions or results, the questions to expect, and the errors that cost marks.
1. Solutions
What is tested: Types of solutions, concentration terms, solubility and Henry's law, vapour pressure and Raoult's law, ideal and non-ideal solutions, colligative properties with molar mass determination, and abnormal molar masses with the van 't Hoff factor.
Key results: p = K_H x (Henry's law). Relative lowering of vapour pressure equals the mole fraction of solute. ΔT_b = iK_b m, ΔT_f = iK_f m, π = iCRT. Positive deviation (ethanol–water, acetone–CS₂) and negative deviation (acetone–chloroform) with their volume and enthalpy changes. Azeotropes, such as nitric acid with about 68% acid by mass.
Typical questions: Concentration in ppm; molar mass from a colligative property; why a mixture of acetone and CS₂ does not have the expected volume; why an azeotrope cannot be separated by fractional distillation.
Common errors: Using molarity where molality is needed. Forgetting i for electrolytes. Mixing up the signs of ΔV and ΔH for positive and negative deviations. Units of K_b and K_f.
2. Electrochemistry
What is tested: Galvanic cells, electrode potentials, the Nernst equation, conductance and molar conductivity, electrolytic cells and electrolysis, batteries, fuel cells and corrosion.
Key results: E_cell = E°_cell − (0.059/n) log Q at 298 K. ΔG° = −nFE°_cell. Λ_m = κ × 1000/C (with κ in S cm⁻¹ and C in mol L⁻¹). Kohlrausch's law and Λ_m = Λ°_m − A√C for strong electrolytes. Faraday's laws. Reactions in the lead storage battery and the H₂–O₂ fuel cell. Sacrificial protection against corrosion.
Typical questions: Nernst equation calculations; unit conversions for molar conductivity; charge needed to deposit a metal; why magnesium protects iron pipes; electrode reactions during electrolysis; a data-based question comparing measured and calculated EMF.
Common errors: Writing Q upside down in the Nernst equation. Forgetting n. Unit errors between S cm² mol⁻¹ and S m² mol⁻¹. Confusing anode and cathode signs in galvanic and electrolytic cells.
3. Chemical Kinetics
What is tested: Rate of reaction, factors affecting rate, integrated rate equations for zero and first order, half-life, temperature dependence (Arrhenius equation) and collision theory.
Key results: For first order, k = (2.303/t) log([R]₀/[R]) and t½ = 0.693/k. For zero order, t½ = [R]₀/2k. log(k₂/k₁) = (Eₐ/2.303R)(1/T₁ − 1/T₂). A plot of log k against 1/T has slope −Eₐ/2.303R. Pseudo first-order reactions, such as hydrolysis with water in excess.
Typical questions: Time for 75% completion of a first-order reaction (two half-lives); activation energy from a graph or two temperatures; order versus molecularity; when rate stays constant (zero order).
Common errors: Confusing order with molecularity. Using ln where the formula has log with 2.303. Unit errors in k for different orders. Reading a slope with the wrong sign.
4. The d- and f-Block Elements
What is tested: Position and electronic configuration of d-block elements, general properties of transition elements, important compounds (potassium dichromate and potassium permanganate), lanthanoids, actinoids, and applications.
Key results: Trends in atomic size, ionisation enthalpy, oxidation states, melting points, colour, magnetic moment (μ = √(n(n + 2)) BM), catalytic behaviour, interstitial compounds and alloy formation. Lanthanoid contraction and its consequences. Oxidising reactions of Cr₂O₇²⁻ and MnO₄⁻ in acid medium.
Typical questions: Which ion has the highest magnetic moment; why a metal melts at a lower temperature than its neighbour; balancing permanganate or dichromate redox equations; why transition metals form complexes; comparisons of lanthanoids and actinoids.
Common errors: Writing electronic configurations of ions by removing 3d electrons before 4s. Unbalanced redox equations. Giving a trend without a reason. Forgetting the exceptional configurations of Cr and Cu.
5. Coordination Compounds
What is tested: Werner's theory, key terms (ligand, coordination number, denticity), IUPAC nomenclature, isomerism, bonding (valence bond theory and crystal field theory), bonding in metal carbonyls, and importance and applications.
Key results: Primary and secondary valency. Strong and weak field ligands (the spectrochemical series). Hybridisation and geometry: sp³ tetrahedral, dsp² square planar, d²sp³ and sp³d² octahedral. Crystal field splitting in octahedral and tetrahedral fields, pairing energy and colour. Geometrical and optical isomerism. Synergic bonding in metal carbonyls.
Typical questions: Naming a complex or writing its formula from the name; predicting geometry and magnetic behaviour; which complex is optically active; conductivity of a series of cobalt(III) ammine complexes; why hydrated copper sulphate is blue. The sample paper's Section E long answer is entirely on this chapter.
Common errors: Alphabetical order of ligands ignored in naming. Wrong oxidation state of the metal. Assuming all four-coordinate complexes are tetrahedral. Using VSEPR instead of VBT or CFT for complexes.
6. Haloalkanes and Haloarenes
What is tested: Classification, nomenclature, the nature of the C–X bond, preparation of haloalkanes and haloarenes, physical properties, chemical reactions (nucleophilic substitution, elimination, reactions with metals), and polyhalogen compounds.
Key results: SN1 (carbocation, racemisation, favoured by 3° substrates) versus SN2 (one step, inversion, favoured by 1° substrates). Ambident nucleophiles: KCN gives nitriles and AgCN gives isocyanides. Low reactivity of haloarenes towards nucleophilic substitution, and the activating effect of electron-withdrawing groups at ortho and para positions. Wurtz and Wurtz–Fittig reactions. Saytzeff's rule in elimination.
Typical questions: Predicting mechanism and stereochemistry from optical rotation; which halide hydrolyses more readily (allylic versus secondary); effect of nitro and methoxy groups on chlorobenzene; IUPAC names.
Common errors: Mixing up SN1 and SN2 conditions. Saying haloarenes are more reactive than haloalkanes. Forgetting the ambident behaviour of CN⁻.
7. Alcohols, Phenols and Ethers
What is tested: Classification and nomenclature, structures of the functional groups, preparation, properties and reactions of alcohols and phenols, some commercially important alcohols, and ethers.
Key results: Acidity order and the effect of substituents on phenol acidity (electron-withdrawing groups increase acidity; alkyl groups decrease it). Reactions of phenol: Kolbe's reaction, Reimer–Tiemann reaction, bromination and nitration. Dehydration of alcohols. Williamson synthesis and cleavage of ethers by HI. Preparation of alcohols from Grignard reagents and carbonyl compounds.
Typical questions: Choosing the Grignard reagent and carbonyl compound for a given alcohol; acidity comparisons using pKa data (a case study in the sample paper); miscibility of ethers with water; distinguishing tests.
Common errors: Reversing the pKa–acidity relationship (lower pKa means stronger acid). Wrong Grignard combinations. Leaving out reaction conditions such as temperature or catalyst.
8. Aldehydes, Ketones and Carboxylic Acids
What is tested: Nomenclature and structure of the carbonyl and carboxyl groups, methods of preparation, physical properties, chemical reactions and uses. At 8 marks, this is the heaviest organic chapter.
Key reactions: Rosenmund reduction, Stephen reaction, Etard reaction, Gattermann–Koch reaction, nucleophilic addition (HCN, NaHSO₃, alcohols, ammonia derivatives), Clemmensen and Wolff–Kishner reductions, aldol and cross-aldol condensation, Cannizzaro reaction, Tollens' and Fehling's tests, Hell–Volhard–Zelinsky reaction, and decarboxylation. Acidity of carboxylic acids and the effect of substituents.
Typical questions: Identifying name reactions and missing products (aldol, Etard and Wolff–Kishner in the sample paper); why pH around 3.5 is used for adding ammonia derivatives; why dry HCl is used with alcohols; distinguishing tests using NaHCO₃ and 2,4-DNP; orders of reactivity.
Common errors: Aldol attempted on aldehydes without α-hydrogens (they undergo Cannizzaro instead). Missing reagents over the arrow. Confusing Clemmensen (Zn-Hg/HCl) with Wolff–Kishner (NH₂NH₂, KOH, ethylene glycol). Wrong reactivity order of aldehydes and ketones.
9. Amines
What is tested: Structure, classification and nomenclature of amines, preparation, physical properties, chemical reactions, and diazonium salts: preparation, properties, reactions and use in synthesising aromatic compounds.
Key reactions: Gabriel phthalimide synthesis (primary aliphatic amines only), Hoffmann bromamide degradation, carbylamine reaction, Hinsberg's test, acetylation to control the reactivity of aniline, diazotisation, Sandmeyer and Gattermann reactions, replacement by fluorine (Balz–Schiemann), and coupling reactions. Basicity order in gas phase and in water.
Typical questions: Basicity and volatility comparisons from data; two-step conversions (nitrobenzene to fluorobenzene, benzoic acid to benzylamine); why nitration of aniline gives meta product; why acetylation is needed for monosubstitution; which reaction gives a foul-smelling product.
Common errors: Using Gabriel synthesis for aromatic amines. Wrong basicity order of methylamines in water. Forgetting that diazotisation needs 273–278 K. Mixing up Hinsberg results for primary and secondary amines.
10. Biomolecules
What is tested: Carbohydrates, proteins, enzymes, vitamins, nucleic acids and hormones, as listed in the 2026-27 syllabus.
Key results: Classification of carbohydrates; reactions of glucose and the evidence for its cyclic structure; anomers; reducing and non-reducing sugars; sucrose, maltose, lactose, starch, cellulose and glycogen. Amino acids (essential and non-essential, acidic, basic and neutral), peptide bonds, primary to quaternary structure, and denaturation. Vitamins and deficiency diseases. DNA versus RNA and their bases.
Typical questions: Classifying an amino acid from its formula; why milk curdles with lemon juice (denaturation of casein); completing a DNA base sequence; identifying a carbohydrate from test results (a case study in the sample paper).
Common errors: Calling sucrose a reducing sugar. Mixing up fat-soluble and water-soluble vitamins. Pairing adenine with uracil in DNA.
How to study each branch
Physical chemistry: formulas plus units
Keep one formula sheet for Solutions, Electrochemistry and Kinetics with units beside every symbol. Practise numericals without a calculator: the board sets numbers that simplify, so if your arithmetic is getting ugly, check the method. Aim for a few numericals every day rather than a large batch once a week.
Inorganic chemistry: trends with reasons
Inorganic questions ask "why". Learn each trend with its reason: why melting points peak in the middle of the series, why Mn³⁺ is a strong oxidising agent, why lanthanoid contraction makes Zr and Hf so similar. For coordination compounds, practise naming and geometry until they are automatic.
Organic chemistry: reaction maps and conversions
Make one reaction map per chapter, with reagents and conditions written over every arrow. Then practise conversions: two- and three-step routes between functional groups. Learn name reactions with an example each. Mechanisms help you remember, but the board asks mostly for products, reagents, reasons and orders of reactivity.
Step marking and answer presentation
CBSE marks chemistry answers step by step. In numericals, the formula, the substitution and the final answer with units each carry marks. In organic questions, the reagent and conditions are often worth as much as the product. Here is a 2-mark Nernst equation answer set out the way examiners like to see it:
Calculate the EMF of the cell Zn | Zn²⁺ (1.0 M) || Cu²⁺ (0.10 M) | Cu at 298 K, given E°cell = 1.10 V.
Cell reaction: Zn + Cu²⁺ → Zn²⁺ + Cu, so n = 2.
E_cell = E°cell − (0.059/n) log([Zn²⁺]/[Cu²⁺])
= 1.10 − (0.059/2) log(1.0/0.10) = 1.10 − 0.0295 × 1
E_cell ≈ 1.07 V.
Writing the cell reaction first gives you n and the correct form of Q. That single line prevents the two most common Nernst errors. A lower EMF than E° also makes sense here, because the product ion is more concentrated than the reactant ion.
Presentation rules that protect your marks
Write the formula before substituting, with units for every quantity.
Write reagents above and conditions below every reaction arrow.
Draw structures clearly; a wrong bond position changes the compound.
For "account for" questions, give one clear reason per part, not a paragraph.
Underline the final answer in numericals, with its unit.
Number every answer exactly as in the paper, including sub-parts.
If you attempt both internal choices, cross out the one you do not want marked.
Month-by-month plan: April to the board exam
| Month | Focus | Practice target |
|---|---|---|
| April–May | Solutions; Electrochemistry | All NCERT exercises; start the physical formula sheet |
| June | Chemical Kinetics; revise Class 11 organic basics | Numericals daily; revise GOC and nomenclature over the holidays |
| July | d- and f-Block Elements | First periodic test; start the practical record and titration practice |
| August | Coordination Compounds | Naming and geometry drill; salt analysis in the lab |
| September | Haloalkanes and Haloarenes; Alcohols, Phenols and Ethers | Reaction maps; revise all physical chemistry |
| October | Aldehydes, Ketones and Carboxylic Acids | Name reactions with examples; choose and start the project |

| January | Practical exam, record and viva; pre-boards | Three full papers a week, checked against a marking scheme |
| February | Final revision | See the last-30-days checklist below |
Schools teach chapters in different orders, so adjust the months to your timetable. The principle stays the same: finish by the end of November, and do not let organic chemistry slide to the last few weeks.
The last 30 days: a checklist
Solve one full paper every alternate day in exactly 3 hours.
Mark each paper against the CBSE marking scheme and update the error log.
Revise the physical chemistry formula sheet daily, with units.
Redo every NCERT intext and exercise numerical in the three physical chapters.
Write out each organic reaction map from memory once a week.
List all name reactions with one example each and test yourself.
Practise ten conversions a day across all organic chapters.
Revise d-block trends and reasons on a single page.
Name and draw ten coordination compounds with geometry and magnetism.
Practise one data-based case study a day.
Keep the final week for revision and rest, not new material.
Common mistakes that cost marks (and the fix for each)
Molarity used for molality – Colligative formulas use molality (mol per kg of solvent).
van 't Hoff factor forgotten – Apply i for every electrolyte in colligative problems.
Deviation signs swapped – Positive deviation: ΔV > 0 and ΔH > 0; negative deviation: both negative.
Q inverted in the Nernst equation – Products over reactants, with n from the balanced equation.
Conductivity units wrong – Convert S cm⁻¹ and mol L⁻¹ carefully before using Λ_m = κ × 1000/C.
Order confused with molecularity – Order is experimental; molecularity is for elementary steps only.
log and ln mixed – Use 2.303 log throughout if the formula is written that way.
Ion configurations wrong – Remove 4s electrons before 3d when forming transition metal ions.
Unbalanced redox equations – Balance atoms, then charge, then check.
Trend without reason – Every inorganic "why" needs a reason, not just the order.
Ligands not alphabetical – Name ligands in alphabetical order, ignoring numerical prefixes.
Wrong oxidation state – Work out the metal's oxidation state before naming or predicting magnetism.
All four-coordinate complexes called tetrahedral – Strong field ligands can give square planar geometry.
SN1 and SN2 mixed – Link substrate, solvent and stereochemistry to each mechanism.
KCN and AgCN outcomes swapped – KCN gives nitriles; AgCN gives isocyanides.
pKa read the wrong way – Lower pKa means a stronger acid.
Aldol on aldehydes without α-hydrogen – Those undergo Cannizzaro reaction instead.
Reagents missing over the arrow – Write reagent and conditions for every step.
Gabriel synthesis for aniline – Gabriel gives primary aliphatic amines only.
Diazotisation temperature missing – Write 273–278 K; it is part of the answer.
Sucrose called reducing – Sucrose is non-reducing; maltose and lactose are reducing.
Studying removed chapters – p-block, solid state and surface chemistry are not board theory topics in 2026-27.
Data questions rushed – Read the table or graph twice; the answer is usually in it.
Time lost on long answers – In five 1-mark-part questions, keep each part to two or three lines.
Balancing boards with NEET, JEE and CUET
The Class 12 chemistry syllabus overlaps heavily with NEET, JEE and CUET, but the entrance exams are set by a different body and can cover more.
Board – Rewards balanced equations, conditions, reasons and step-by-step numericals.
NEET – Fast, accurate recall across Class 11 and 12 NCERT, with inorganic and organic facts tested closely.
JEE – Deeper physical chemistry numericals and organic mechanisms, and multi-concept questions.
CUET – MCQs close to NCERT level; board preparation covers most of it.
Syllabus gaps – Topics outside the CBSE Class 12 board syllabus, such as p-block chemistry, may still appear in entrance syllabi. Check the current official syllabus for your exam before dropping any topic.
A practical pattern: learn each chapter to board level from NCERT first, then add entrance-level MCQs in the same week. From December, alternate board papers and entrance practice, because written answers with conditions and reasons are a separate skill. For entrance support, see NEET chemistry tutors.
For the other science papers, see our CBSE Class 12 Physics guide and CBSE Class 12 Maths guide.
When does a home tutor help?
Organic feels like memorising – The student cannot see patterns between reactions and forgets them within weeks.
Weak Class 11 foundations – Gaps in mole concept, GOC or nomenclature keep causing errors.
Physical numericals – Methods are known but units and arithmetic keep going wrong.
Coordination compounds – Naming, geometry and CFT feel confusing.
Board and NEET or JEE together – The student needs a plan that covers both.
No feedback on written work – Mock papers are attempted but never marked against a scheme.
What a good Class 12 chemistry session looks like
A good session mixes explanation with the student doing the work: writing conversions, balancing equations and solving numericals while the tutor watches. The tutor corrects reagents, conditions and units, not just the final product, builds reaction maps with the student, and sets a timed paper every few weeks, marked the way a CBSE examiner would.
How to choose a tutor: a demo-class checklist
Did the tutor ask which branch and chapters worry the student most?
Do they know the 2026-27 syllabus, including the formative-only topics?
Did the student write reactions or solve problems during the demo?
Did they correct reagents, conditions and units, not only answers?
Did they explain an idea a second way when the first did not work?
Did they propose a plan with dates, including practicals and mock papers?
If NEET or JEE matters, did they explain how to balance it with the board?
On NXTutors, you tell us what the student needs and we match you with two or three tutors. The first demo class is free, tutors who join go through an ID check, and switching tutors is free if the fit is not right. Across NXTutors, most home-tuition sessions fall between ₹800 and ₹2,500 an hour; Classes 11–12, IB/IGCSE and JEE/NEET sit toward the upper end; specialists for IB HL or JEE Advanced can charge more. Where a tutor falls depends on their experience, the city, and whether classes are at home or online.
Explore Class 12 chemistry home tutors, find a chemistry home tutor in Gurgaon, or book a free demo class to see how a session works before you decide.
Chemistry rewards organised revision. Keep a formula sheet for physical, a trends sheet for inorganic, and reaction maps for organic; practise papers under time; and read every data question twice. That is how marks are secured.
Frequently asked questions
Is p-block in the CBSE Class 12 Chemistry syllabus for 2026-27?
The p-block elements are not in the CBSE Class 12 Chemistry syllabus for 2026-27, which has ten chapters from NCERT Part I and Part II. Older guides that call p-block high priority for the board are out of date. The topic may still be part of some entrance exam syllabi, so check the official syllabus for yours.
Will Polymers and Chemistry in Everyday Life come in the Class 12 Chemistry board exam?
Polymers and Chemistry in Everyday Life will not come in the 2026-27 Class 12 Chemistry board theory paper. The curriculum lists them, with Surface Chemistry and Isolation of Elements, as assessed only formatively, so they do not add to board marks. Your school may still teach and test them, and surface chemistry still appears in the practical syllabus.
Which branch of Class 12 Chemistry should I revise first?
Start Class 12 Chemistry revision with whichever branch is weakest, but do not leave organic chemistry to the end. Organic carries 33 of the 70 theory marks, physical 23 and inorganic 14, and organic reactions need repeated revision to stick. Electrochemistry, at 9 marks, is the heaviest single chapter.
Are calculators or log tables allowed in the Class 12 Chemistry exam?
Calculators and log tables are not allowed in the CBSE Class 12 Chemistry exam, as the 2026-27 sample paper states. Numericals are set with manageable numbers, so if the arithmetic is getting ugly, check the method. Practise numericals by hand so that simplifying logs and powers of ten becomes routine.
How are the 30 practical marks split in CBSE Class 12 Chemistry?
The 30 practical marks in CBSE Class 12 Chemistry are split into volumetric analysis 8, salt analysis 8 and a content-based experiment 6. Project work and the class record with viva add 4 each. Volumetric analysis is the KMnO₄ titration against oxalic acid or Mohr's salt. Salt analysis means identifying one cation and one anion, with insoluble salts excluded.
What does the CBSE Class 12 Chemistry paper look like for 2027?
The CBSE Class 12 Chemistry paper for 2027 is a 3-hour, 70-mark theory paper with 33 compulsory questions in five sections, A to E. Section A has 16 MCQs, including assertion–reason, followed by 2-mark, 3-mark, two 4-mark case-based and three 5-mark questions. The 2026-27 sample paper states there is no change in design, and 60 percent of marks reward applying and reasoning.
How should a Class 12 student balance Chemistry boards with NEET or JEE?
A Class 12 student can balance Chemistry boards with NEET or JEE by learning each chapter to board level from NCERT first, then adding entrance-level MCQs in the same week. From December, alternate board papers and entrance practice, since written answers with conditions and reasons are a separate skill. Check each entrance exam's official syllabus, which can include topics such as p-block chemistry.
