Chapter 1: Some Basic Concepts of Chemistry
Introduction to chemistry, laws of chemical combination, mole concept, mass and mole calculations, and stoichiometry.
Chapter 2: Structure of Atom
Atomic models (Rutherford, Bohr), quantum mechanical model, quantum numbers, orbitals, and electronic configuration.
Chapter 3: Classification of Elements and Periodicity in Properties
Modern periodic table, periodic trends like atomic radius, ionization energy, electronegativity, and element properties.
Chapter 4: Chemical Bonding and Molecular Structure
Bond formation (ionic, covalent), VSEPR theory, hybridization, molecular geometry, and bond characteristics.
Chapter 5: Chemical Thermodynamics
Energy in chemical processes, enthalpy, internal energy, entropy, first law of thermodynamics, and spontaneity.
Chapter 6: Equilibrium
Chemical and ionic equilibrium, equilibrium constants, Le Chatelier’s principle, acids, bases, pH, buffers.
Chapter 7: Redox Reactions

Chapter 8: Organic Chemistry – Some Basic Principles and Techniques
IUPAC nomenclature, reaction mechanisms, inductive/resonance effects, and purification of organic compounds.
Chapter 9: Hydrocarbons
Alkanes, alkenes, alkynes, benzene, their structure, properties, reactions (combustion, substitution, addition).
CBSE Class 11 Chemistry is assessed out of 100 marks, divided into:
Theory: 70 marks
There are 9 chapters in total, covering Physical, Inorganic, and Organic Chemistry. These include fundamental topics like the Structure of Atom, Thermodynamics, Equilibrium, and Hydrocarbons.
Yes, CBSE has updated the Class 11 Chemistry syllabus for 2025–26. It aligns with NEP 2020, focuses on competency-based learning, and includes recent trends like Green Chemistry and Application-Based Questions.
The final exam now includes:
20% MCQs
50% application-based or competency questions
30% short and long answer questions
This structure encourages conceptual understanding over rote learning.
The practical section (30 marks) includes:
Volumetric Analysis (8 marks)
Salt Analysis (8 marks)
Content-Based Experiments (6 marks)
Project Work (4 marks)
Yes, Organic Chemistry forms a major part of the syllabus. It includes:
