Chemistry Home Tutor for Class 12

CBSE Class 12 chemistry 2026-27: the ten units and their marks

The theory paper is 70 marks and three hours long, with 30 marks for practical work. The ten units follow the two NCERT Class 12 chemistry textbooks: Part I covers the physical and inorganic units, Part II the organic ones.

Add the branches up and the picture is clear: organic chemistry is 33 marks, physical 23 and inorganic 14. Electrochemistry, at 9 marks, is the heaviest single unit, and Aldehydes, Ketones and Carboxylic Acids, at 8, is the heaviest organic one. A Class 12 chemistry tutor should plan time roughly in that proportion, adjusted for the student's weak branch.

How the Class 12 chemistry paper is built

CBSE's 2026-27 question-paper design does not fix a chapter-wise weightage within each question type, but it does fix the mix of thinking skills:

There is no overall choice, and about a third of the questions offer an internal choice. In recent CBSE papers, the applying and analysing marks typically come through multiple-choice and assertion-reason items, case-based questions built on an unseen passage or data, organic conversions and "give reasons" questions. The exact section layout is set in CBSE's sample question paper each year, and a tutor should use the latest one as the model for practice papers.

The practical lesson: a student who has only read NCERT will know the facts for the 40% but may freeze on a case study about an unfamiliar cell or reaction. Regular practice with unseen questions is the fix.

Organic chemistry: named reactions and conversions

Five organic units carry 33 marks, and most students either love them or dread them. The difference is usually method. Students who try to memorise each reaction as a separate fact run out of memory by Amines. Students who learn why reactions happen, through electron-rich and electron-poor sites, leaving groups and stability of intermediates, find that the same few ideas repeat.

Named reactions are guaranteed marks and must be known exactly: reagent, conditions and product. The main ones in the NCERT Class 12 organic chapters:

Conversions are where named reactions become marks. A typical question asks the student to convert, say, benzene to a particular amine or an alcohol to a ketone with one more carbon, in two or three steps. A tutor should build this skill deliberately:

• A reaction map. One large sheet linking every functional group to the others by reagent. The student builds it, not the tutor, and adds to it after every chapter.
• Daily conversions. Three or four short conversions in every session from October onwards, mixing chapters so the student has to search the map.
• Mechanisms where the syllabus asks for them. SN1 and SN2, dehydration of alcohols, nucleophilic addition to carbonyls. Writing curved arrows correctly is itself marked.
• "Give reasons" practice. Why phenol is more acidic than ethanol, why aniline is a weaker base than ethylamine. These answers come from electronic effects learned in Class 11.

Our article on CBSE Class 12 organic and inorganic chemistry has more chapter-level detail.

Physical chemistry: solutions, electrochemistry and kinetics

The three physical units are worth 23 marks and are the most reliable marks on the paper for a student who has practised. They are also where careless arithmetic costs most.

A good tutor gives these units a numerical set every week, even while teaching organic, so the skills do not fade. Practice should be done without a calculator or log tables, using sensible approximations, because CBSE's sample paper allows neither in the exam hall; the student should always write units and state the final answer clearly.

Inorganic chemistry: d- and f-block and coordination compounds

These two units carry 14 marks together. Inorganic chemistry in Class 12 is largely NCERT recall with reasoning behind it, which suits students who revise steadily and hurts those who leave it until February.

d- and f-Block Elements. Electronic configurations of transition elements, trends in atomic size, ionisation enthalpy, oxidation states, colour, magnetic behaviour and catalytic properties; the preparation and properties of potassium dichromate and potassium permanganate; and the lanthanoids and actinoids, including lanthanoid contraction and its consequences. Most questions are "explain why" questions: why Zn, Cd and Hg are soft, why Mn shows the most oxidation states in the first series, why Cu⁺ is unstable in water. A tutor should drill these as short spoken answers until they are fluent.

Coordination Compounds. Werner's theory, key terms such as ligand, coordination number and denticity, IUPAC nomenclature, structural and stereoisomerism, bonding through valence bond theory and crystal field theory, metal carbonyls, and applications. Nomenclature and isomerism are reliable marks; crystal field splitting and predicting magnetic behaviour need hybridisation from Class 11, so a student weak in Class 11 bonding will need a short refresher here.

Topics taught in Class 12 but assessed only in school

The 2026-27 curriculum keeps four topics in the syllabus for formative assessment only, meaning they are not part of the board theory paper:

• Surface chemistry. Adsorption, colloids, coagulation and emulsions.
• General principles and processes of isolation of elements. Concentration, oxidation, reduction, electrolytic methods and refining.
• Polymers. Polymerisation, homopolymers and copolymers.
• Chemistry in everyday life. Chemicals in medicines and in food.

For a board-only student these deserve only light attention. Some related practical experiments, such as preparing sols, remain in the practical list, so the basic ideas are still worth knowing. Students preparing for entrance exams should check their exam's own syllabus rather than assume the board list applies.

The Class 12 chemistry practical exam

Thirty marks, nearly a third of the subject total, come from the practical exam. The curriculum splits them as volumetric analysis 8, salt analysis 8, a content-based experiment 6, project work 4, and class record and viva 4.

• Volumetric analysis. Titrating potassium permanganate against standard oxalic acid or Mohr's salt, with the student preparing the standard solution by weighing. The calculation and the equivalence relationship must be secure.
• Salt analysis. Identifying one cation and one anion in a given salt. Students do well when they understand the logic of the group scheme instead of memorising a flowchart.
• Content-based experiments. Options include kinetics experiments with sodium thiosulphate, enthalpy of neutralisation, cell potential variation, paper chromatography, preparation of inorganic and organic compounds, and functional-group tests.
• Viva and record. Questions on principle, procedure, precautions and sources of error. Easy marks if the student has prepared a few answers for each experiment.

A tutor can rehearse viva questions, check titration calculations and walk through the salt-analysis logic so the student arrives at the lab confident.

A month-by-month Class 12 chemistry plan

This plan assumes a student who starts with a tutor in April and sits the CBSE board exam in February or March. The school order may differ; the tutor should adapt it.

A student starting in October or November should not try to follow the whole plan. The tutor should go straight to the highest-mark units the student is weakest in, usually one organic block and electrochemistry, and use past papers from the start.

Where Class 12 chemistry marks are lost

• Incomplete reactions. Missing reagents or conditions over the arrow, or products written without by-products where they are asked for.
• Wrong IUPAC names. A correct structure with the wrong name loses marks, especially in coordination compounds.
• Units and significant figures. Molar conductivity units, rate constant units by order, and answers left with too many digits.
• Vague reasons. "Because of stability" is not an answer. The examiner wants the specific effect: resonance, inductive effect, lanthanoid contraction.
• Skipping case-based questions. Students panic at unfamiliar contexts. The chemistry inside is always from the syllabus.
• Leaving inorganic too late. Two chapters of recall cannot be learned in the last fortnight.

A typical tutoring week in Class 12

With two sessions a week, a tutor can keep all three branches moving even while the school teaches one chapter at a time. A pattern that works well from October onwards:

Parents should expect a short update after each session: what was covered, what the homework is and anything the tutor is worried about. If weeks go by without seeing organic conversions or physical numericals, ask why.

Boards and entrance exams in the same year

Many Class 12 students are preparing for NEET or JEE at the same time as the boards. The syllabi overlap heavily, but the skills do not. Board papers reward complete, well-written answers with reasons and equations; entrance papers reward speed and the ability to pick the right option under time pressure. A tutor who works with both should keep separate practice for each, and should be especially careful about topics that differ between the two lists, such as the p-block elements, which are in the NEET syllabus but assessed only in school under the current CBSE curriculum. From January, most students shift their weight to the board exam until it is over, then back to entrance practice. See our JEE chemistry guide for the engineering side.

Choosing a Class 12 chemistry tutor

In the demo, ask the tutor to set your child a two-step organic conversion and a Nernst-equation numerical, and watch how they help. A strong Class 12 tutor will let the student attempt first, find the exact step that went wrong and fix it. Ask what they know about this year's formative-only topics and the latest sample paper. And ask how they would divide the remaining months between the three branches for your child specifically.

If your child is also preparing for NEET, look for a tutor who can handle both; our NEET chemistry tutor guide explains the difference in approach. Many Class 12 students also need support in physics; see our Class 12 physics tutor guide. For the wider picture, read our main guide to a chemistry home tutor, and for the year before, the Class 11 chemistry guide.

Fees, frequency and getting started

Across NXTutors, most sessions fall between ₹800 and ₹2,500 an hour, depending on the tutor's board-exam experience, whether entrance preparation is included, home or online sessions, travel in your area and the number of sessions a week. You see each shortlisted tutor's fee before the demo; our pricing guide explains the factors.

Two sessions a week through the year and three from December to the boards suits most students. Home tuition helps when a student needs close supervision; online tuition gives a wider choice of experienced Class 12 tutors and works well if the tutor can see the notebook.
