How to use this list

  • Foundations first. Some Basic Concepts of Chemistry, Structure of Atom, Classification of Elements & Periodicity and Chemical Bonding & Molecular Structure look small, but later chapters depend on them.
  • Then the very high chapters. They earn the most marks per hour. Revise them more than once.
  • Never drop a chapter just because its tier is lower. One question can be the difference in rank.
  • Track it. Mark each chapter as started, done or due for revision, so you always know what is left.

How we rank chapters

We compared published analyses of NEET papers from 2020 to 2024, including one that counted more than 250 questions per subject. The sources agree on which chapters come up most, but not on exact percentages, so we show tiers instead of numbers that look more precise than they are.

Chapters marked estimate have thin data, so treat their tier as a rough guide. Chapters marked Foundation may carry fewer direct questions, but other chapters depend on them. Do not skip them.

The chapter list follows the current NMC syllabus. The official 2027 syllabus comes with the information bulletin on neet.nta.nic.in. We update this page when it changes.

Questions students ask

How many chapters are in NEET 2027 Chemistry?

NEET Chemistry has 23 chapters: 12 from Class 11 and 11 from Class 12. The full list is on this page.

Which NEET Chemistry chapters have the highest weightage?

Aldehydes, Ketones & Carboxylic Acids, Chemical Bonding & Molecular Structure and Hydrocarbons come up the most in past NEET papers. Give them the most time, but finish the foundation chapters first.

Which Chemistry chapters should I study first?

Start with the foundation chapters: Some Basic Concepts of Chemistry, Structure of Atom, Classification of Elements & Periodicity, Chemical Bonding & Molecular Structure and Equilibrium. Later chapters build on them, even when they carry fewer direct questions. Then spend most of your time on the very high and high weightage chapters.

Is this the official NEET 2027 Chemistry syllabus?

It follows the current NMC syllabus. The official 2027 syllabus is published with the information bulletin on neet.nta.nic.in, and we update this page when it changes.
