What Is the NCERT Class 11 Chemistry Book?
NCERT Class 11 Chemistry Book is the chemistry textbook prescribed by the CBSE board and published by the National Council of Educational Research and Training (NCERT). It is the single most important resource for Class 11 Science students, since CBSE frames its board question papers directly from NCERT content, and both JEE and NEET draw a large share of their Chemistry questions from concepts first introduced here.
The Chemistry Book for class 11 is published in two parts and contains 9 units.

Unit-wise (Chapter-wise) PDFs for NCERT Class 11 Chemistry can be downloaded for free from the official NCERT website (ncert.nic.in) or from the links provided in the table below on eSaral. Downloading individual units — rather than the entire book — lets you focus on one topic at a time and is especially useful during revision weeks before board exams.

NCERT Class 11Chemistry vs the CBSE Board Syllabus (2026-27)
For the 2026–27 academic session, CBSE has prescribed 9 theory units in Class 11 Chemistry, carrying a total of 70 marks. Students may find older NCERT resources with additional chapters, so it is important to follow the latest CBSE syllabus while preparing for school examinations. The unit-wise marks distribution is provided below for easy reference.
CBSE Class 11 Chemistry Syllabus 2026-27 — Unit-wise Weightage
| Unit | Chapter | Marks |
|---|---|---|
| I | Some Basic Concepts of Chemistry | 7 |
| II | Structure of Atom | 9 |
| III | Classification of Elements and Periodicity in Properties | 6 |
| IV | Chemical Bonding and Molecular Structure | 7 |
| V | Chemical Thermodynamics | 9 |
| VI | Equilibrium | 7 |
| VII | Redox Reactions | 4 |
| VIII | Organic Chemistry – Some Basic Principles and Techniques | 11 |
| IX | Hydrocarbons | 10 |
| Total (Theory) | 70 | |
| Practicals | 30 | |
| Grand Total | 100 |
This is exactly why NEET and JEE aspirants are often advised not to skip the "extra" chapters (States of Matter, Hydrogen, s-Block, Environmental Chemistry) even though they carry less direct board weightage — competitive exams test the complete NCERT Chemistry Class 11 syllabus, not just the 9 board-weighted units.
Key Concepts and Formulas Introduced in NCERT Chemistry Class 11
Is NCERT Enough for JEE and NEET Chemistry Preparation?
For NEET-UG
NCERT Class 11 and Class 12 Chemistry books together cover approximately 60–70% of NEET Chemistry in terms of direct conceptual questions. For NEET, reading NCERT word-for-word — including footnotes and diagrams — is essential. Every reaction mechanism in Organic Chemistry (Chapters 12 and 13) and every property listed in s-block and p-block chapters can become a NEET question. Once you've built this base, check your exact chapter weightage with eSaral's NEET Chemistry Weightage breakdown to prioritize revision
For JEE Main
JEE Main Chemistry is roughly split into three segments: Physical, Inorganic, and Organic. NCERT covers Inorganic and conceptual Organic very well. Physical Chemistry — particularly Thermodynamics, Equilibrium, and Electrochemistry — needs additional numerical practice beyond NCERT exercises. Struggling to apply these concepts under timed conditions? eSaral's JEE Test Series is built specifically around this NCERT-first approach.
For JEE Advanced
JEE Advanced requires a depth of reasoning that goes beyond NCERT. However, every JEE Advanced Chemistry question has its roots in NCERT concepts. The book must be mastered first before moving to advanced resources.
For solutions to Class 11 Physics and Maths alongside Chemistry preparation, refer to NCERT Solutions for Class 11 Physics — particularly useful for students managing multi-subject boards and JEE prep simultaneously. The book must be mastered first before moving to advanced resources — JEE Advanced Chapterwise PYQ is a good next step to test that mastery.

Frequently Asked Questions
Find answers to common questions.
How many marks does each of the 9 units carry in the CBSE Class 11 Chemistry board exam?
Organic Chemistry – Some Basic Principles and Techniques carries the highest weightage at 11 marks, followed by Hydrocarbons at 10 marks, and Structure of Atom and Chemical Thermodynamics at 9 marks each, out of a 70-mark theory paper.
Why does the NCERT book still show 14 chapters if the syllabus has only 9 units?
The original NCERT textbook was printed with 14 chapters, but CBSE's syllabus rationalisation removed 5 of them from the examinable syllabus starting 2023-24. Students should follow the current 9-unit syllabus for board exam preparation and can skip the 5 deleted chapters unless preparing for JEE or NEET.
Which chapters were removed from the Class 11 Chemistry syllabus?
Five chapters were removed during CBSE's syllabus rationalisation, starting 2023-24 and continuing through 2026-27: States of Matter, Hydrogen, the s-Block Elements, the p-Block Elements, and Environmental Chemistry. These are excluded from the current board syllabus and do not need to be prepared for CBSE board exams.
How many chapters/units are there in Class 11 Chemistry for 2026-27?
There are 9 units in the NCERT Class 11 Chemistry syllabus for 2026-27: Some Basic Concepts of Chemistry, Structure of Atom, Classification of Elements and Periodicity in Properties, Chemical Bonding and Molecular Structure, Chemical Thermodynamics, Equilibrium, Redox Reactions, Organic Chemistry – Some Basic Principles and Techniques, and Hydrocarbons.
Which units of the current syllabus are commonly tested in NEET?
Structure of Atom, Chemical Bonding, and Equilibrium from the current 9-unit syllabus are frequently tested in NEET, often almost verbatim from the NCERT text. NEET aspirants should also revise the removed chapters, like Hydrogen and the p-Block Elements, since NEET's syllabus is broader than the current CBSE board syllabus.
Which of the 9 units are most important for JEE Main?
The highest-weightage units for JEE Main from the current 9-unit syllabus are Chemical Bonding and Molecular Structure, Chemical Thermodynamics, Equilibrium, Organic Chemistry Basics, and Hydrocarbons. The Physical Chemistry units among these need extra numerical practice beyond the textbook exercises alone.
Should JEE and NEET aspirants still study the 5 removed chapters?
Yes. Even though States of Matter, Hydrogen, the s-Block Elements, the p-Block Elements, and Environmental Chemistry are no longer part of the CBSE board syllabus, JEE and NEET continue to test the complete NCERT Chemistry syllabus, so these chapters should not be skipped by competitive exam aspirants.
Is the NCERT Class 11 Chemistry book enough for CBSE board exams?
Yes. CBSE frames its Class 11 Chemistry board papers directly from the 9 current NCERT units, so the book alone is sufficient for roughly 90-95% of the exam. Solving all end-of-chapter questions and understanding every in-text example across these 9 units is the minimum required preparation.
What is the difference between the NCERT Class 11 Chemistry book and NCERT Solutions for Class 11 Chemistry?
The NCERT Class 11 Chemistry book is the textbook containing chapter content and unanswered exercise questions for the current 9-unit syllabus. NCERT Solutions are the separate, step-by-step worked answers to those same textbook questions, available on eSaral's NCERT Solutions for Class 11 Chemistry page.
Which of the 9 units do students find the toughest?
Structure of Atom, Chemical Thermodynamics, and Equilibrium are the units students most commonly find difficult, largely due to their conceptual depth and heavy numerical component compared to more descriptive units like Redox Reactions.
What is the latest edition of the NCERT Class 11 Chemistry book?
The current NCERT Class 11 Chemistry syllabus is the edition prescribed for the 2026-27 academic session, following CBSE's rationalisation to 9 units, and is published by the National Council of Educational Research and Training (NCERT).
