What Is the NEET Chemistry Syllabus 2027?

It is a 20-unit list from the National Medical Commission (NMC), split into Physical, Inorganic, and Organic Chemistry. The unit numbers below (1–20) follow the official order and match the chemistry list in our complete NEET syllabus 2027 guide.

Chemistry has 45 compulsory questions for 180 marks (+4 for a correct answer, −1 for a wrong one). Note that older pages, including an earlier version of this one, said 50 questions; that is outdated. Read the NEET exam pattern for the full paper structure.

Has anything changed for 2027? Not officially: NMC left the syllabus unchanged for 2026, and no 2027 revision has been announced. The current status is tracked on the main NEET syllabus 2027 page.

NEET Inorganic Chemistry Syllabus 2027: Units 9 to 12

Inorganic Chemistry has only 4 units, so every line of NCERT matters. The p-block unit is the one students most often over-study, so read its scope carefully.

Unit 9: Classification of Elements and Periodicity in Properties

• Modern periodic law and the present form of the periodic table; s, p, d and f blocks

Unit 10: p-Block Elements

• Groups 13 to 18: electronic configuration
• General trends in physical and chemical properties across periods and down groups
• Unique behaviour of the first element in each group

Scope tip: the official text asks for general trends and the unique behaviour of the first element, not a compound-by-compound study. Use NCERT to understand those trends rather than memorising every compound. If your current NCERT edition has no dedicated p-block chapter, use the older NCERT p-block chapters for the same trends.

Which Chemistry Units Come from Class 11 and Which from Class 12?

Class 11 supplies the foundations, and Class 12 supplies most of the advanced numericals and organic chemistry. NMC lists units without a class split, so this table maps them to the usual NCERT arrangement.

Use NCERT Solutions for Class 11 and Class 12 alongside the NCERT books while you work through the units.

Which Chemistry Chapters Are Not in the NEET Syllabus 2027?

Nine NCERT chapters are not in the NMC unit list: States of Matter, Hydrogen, s-Block Elements, Solid State, Surface Chemistry, Metallurgy, Polymers, Chemistry in Everyday Life and Environmental Chemistry. You can skip them for NEET even though they may still appear in your school textbook.

Sub-topics trimmed inside chapters that remain

• Importance and scope of chemistry (introduction)
• Atomic number, isotopes and isobars; shells and subshells
• Third law of thermodynamics
• Cyanides and isocyanides as a separate topic

Added or newly emphasised

NEET Chemistry Chapter-Wise Weightage: Which Chapters Matter Most?

Coordination Compounds was the single biggest chapter in eSaral’s analysis of the 3 May 2026 paper, with 5 questions. Use weightage to order your revision, never to skip a unit.

By section, the same analysis found Physical and Inorganic Chemistry at about 14 questions each, leaving about 17 for Organic Chemistry. Counts differ slightly between analyses because the paper was set in several codes, so treat the numbers as indicative. Read our full NEET 2026 paper analysis, see the code-wise breakdown, and practise with chapter-wise NEET PYQs with solutions and NEET important questions.

Weightage for Biology and Physics is covered on the main syllabus page.

Can You Skip Physical Chemistry for NEET?

No. Physical Chemistry brought roughly 14 of 45 chemistry questions (about 56 marks) in one analysis of the 3 May 2026 paper. Skipping it gives away more marks than most students recover elsewhere.

The good news is that most Physical Chemistry questions are formula-driven and can be learned. Start with the units that show up most:

1. Mole concept and stoichiometry (Unit 1): pure practice, fast to master
2. Equilibrium and Thermodynamics (Units 6 and 4): concept plus a short formula set
3. Electrochemistry and Redox (Unit 7): Nernst equation and conductivity relations
4. Kinetics and Solutions (Units 8 and 5): rate laws, half-life, colligative properties

How to Cover the NEET Chemistry Syllabus Unit by Unit

Treat the three sections differently: practise Physical, re-read Inorganic, and map Organic. A practical split of study time is roughly in line with question share, a little more for Organic.

Fit this into your overall plan from the 6-month NEET 2027 syllabus plan. For revision, use our NEET revision notes, revision videos and mind maps, NEET previous year papers and the NEET test series. If you want expert-led structure, see eSaral NEET courses.
