NCERT Book for Class 11 Chemistry

If you are a Class 11 student preparing for CBSE board exams, JEE, or NEET, the NCERT Chemistry textbook is the single most important resource you need. It covers all the core concepts in a clear, step-by-step manner and is trusted by students, teachers, and parents across India. On this page, you can access the complete NCERT Class 11 Chemistry book for educational reference, available in two parts as per the official curriculum.


About the NCERT Class 11 Chemistry Book

The Class 11 Chemistry textbook published by NCERT is divided into two parts. Together, they cover both inorganic/physical chemistry and organic chemistry in a way that is thorough yet easy to follow. The language is student-friendly, and each chapter includes solved examples, in-text questions, and end-of-chapter exercises to help students practice well.

This book is based on publicly available educational material and is the foundation for CBSE Class 11 Chemistry as well as entrance exams like JEE Main, JEE Advanced, and NEET.


What is Covered in Each Part


Part I – Physical and Inorganic Chemistry

Part I of the Class 11 Chemistry book includes six units covering the following topics:


  • Some Basic Concepts of Chemistry – Introduces the mole concept, atomic mass, significant figures, stoichiometry, and concentration terms like molarity. This is the foundation chapter that makes the rest of chemistry easier.

  • Structure of Atom – Covers subatomic particles, Bohr's model, quantum numbers, orbitals, and the Aufbau principle. Students also learn about the dual nature of matter and Heisenberg's uncertainty principle.

  • Classification of Elements and Periodicity in Properties – Explains Mendeleev's periodic table, the modern periodic law, and trends in atomic radius, ionisation enthalpy, electron gain enthalpy, and electronegativity.

  • Chemical Bonding and Molecular Structure – Discusses ionic bonding, covalent bonding, Lewis structures, VSEPR theory, hybridisation (sp, sp2, sp3), molecular orbital theory, and hydrogen bonding.

  • Thermodynamics – One of the most scoring chapters, it covers system and surroundings, enthalpy, Hess's law, entropy, Gibbs free energy, and spontaneity of reactions.

  • Equilibrium – Explains physical and chemical equilibrium, Le Chatelier's Principle, acids and bases (Arrhenius, Bronsted-Lowry, Lewis), pH, buffer solutions, and solubility product.



Part II – Organic Chemistry

Part II focuses on organic chemistry and includes three units:


  • Redox Reactions – Explains oxidation and reduction in terms of electron transfer, oxidation numbers, balancing redox equations using the half-reaction method, and electrochemical series.

  • Organic Chemistry: Some Basic Principles and Techniques – Introduces functional groups, IUPAC nomenclature, structural isomerism, inductive effect, resonance, hyperconjugation, reaction intermediates, and purification techniques like chromatography and distillation.

  • Hydrocarbons – Covers alkanes, alkenes, alkynes, and aromatic compounds (benzene), including their preparation, properties, reactions, and industrial applications.



Chapters Removed from the Latest Edition

As part of the rationalisation of the NCERT curriculum, the following chapters were removed from the Class 11 Chemistry syllabus in a previous revision and are not part of the current edition:

  • States of Matter

  • Hydrogen

  • The s-Block Elements

  • The p-Block Elements

  • Environmental Chemistry

Students should follow the latest edition of the textbook to make sure they are studying only what is currently in the CBSE syllabus.


How to Study the NCERT Class 11 Chemistry Book Effectively

Scoring well in chemistry is not just about reading the textbook. Here is how you can make the most of it:


  • Read every line carefully. NCERT is known for asking questions directly from the text, especially in board exams. Do not skip the in-text solved examples.

  • Solve all exercises. Every chapter ends with a set of questions. Attempt all of them after finishing the chapter.

  • Use diagrams and tables. For topics like atomic structure, molecular geometry, and hybridisation, drawing diagrams yourself helps you understand and remember better.

  • Practise numericals daily. Chapters like Thermodynamics, Equilibrium, and Redox Reactions have a lot of calculation-based questions. Regular practice is the only way to get comfortable with them.

  • Revise with a summary. Each chapter in the NCERT book ends with a summary. Use it for quick revision before exams.


Why Class 11 Chemistry is Important Beyond Boards

Many students make the mistake of treating Class 11 as a lighter year. In reality, Class 11 Chemistry forms the base for:

  • NEET – A significant portion of questions in the NEET Biology and Chemistry sections are directly based on Class 11 NCERT concepts.

  • JEE Main and Advanced – Physical chemistry from Part I and organic chemistry from Part II are heavily tested in JEE.

  • Class 12 Chemistry – Topics like Chemical Bonding, Equilibrium, and Organic Chemistry carry forward directly into the Class 12 syllabus.

Starting with a strong understanding of Class 11 Chemistry gives students a major advantage in both boards and competitive exams.


Frequently Asked Questions (FAQs)


Q1. Is the NCERT Class 11 Chemistry book enough for CBSE board exams?

Yes, for CBSE board exams, the NCERT Class 11 Chemistry textbook is more than sufficient. Almost all board exam questions are either directly from the book or based on the concepts explained in it. Make sure you solve all the in-text questions and end-of-chapter exercises.


Q2. How many chapters are there in the latest edition of Class 11 NCERT Chemistry?

The current edition of the Class 11 Chemistry book has nine chapters divided across two parts. Part I has six chapters (Units 1 to 6) and Part II has three chapters (Units 7 to 9). Several chapters were removed from an earlier version as part of syllabus rationalisation.


Q3. Is NCERT Chemistry Class 11 useful for NEET preparation?

Absolutely. NEET tests a lot of chemistry concepts from Class 11 NCERT, especially from topics like Basic Concepts of Chemistry, Structure of Atom, Chemical Bonding, Thermodynamics, Equilibrium, and Hydrocarbons. Reading and revising the NCERT book thoroughly is one of the most recommended NEET preparation strategies.


Q4. Can I use Class 11 NCERT Chemistry for JEE preparation?

Yes, NCERT Chemistry is the starting point for JEE preparation. While JEE also requires additional practice from reference books and previous year papers, NCERT gives you a solid conceptual foundation. Organic chemistry in Part II is particularly important for JEE.


Q5. What is the difference between Part I and Part II of the NCERT Class 11 Chemistry book?

Part I focuses on inorganic and physical chemistry, covering topics like atomic structure, the periodic table, chemical bonding, thermodynamics, and equilibrium. Part II focuses on redox reactions and organic chemistry, introducing concepts like functional groups, IUPAC naming, and hydrocarbons. Together, both parts cover the complete Class 11 Chemistry syllabus.
