📘 Class 11 Chemistry – Chapter-wise Summary
Chapter 1: Some Basic Concepts of Chemistry
This chapter lays the foundation of Chemistry. It explains matter, laws of chemical combination, Dalton’s atomic theory, mole concept, molar mass, and stoichiometry. Students learn how to calculate empirical and molecular formulas and solve numerical problems related to chemical reactions.
Chapter 2: Structure of Atom
Introduces the discovery of subatomic particles, atomic models (Thomson, Rutherford, Bohr), and quantum mechanical concepts. It explains quantum numbers, orbitals, electronic configurations, and rules like Aufbau principle, Pauli’s exclusion, and Hund’s rule.
Chapter 3: Classification of Elements and Periodicity in Properties
Discusses the history of the periodic table and modern classification. It explains periodic trends such as atomic radius, ionization enthalpy, electronegativity, and electron gain enthalpy, along with their significance in predicting element behavior.
Chapter 4: Chemical Bonding and Molecular Structure
Explains different types of bonds – ionic, covalent, and coordinate. Covers Lewis structures, VSEPR theory, hybridization, molecular orbital theory, and shapes of molecules. It helps students understand how atoms combine to form compounds.
Chapter 5: Chemical Thermodynamics
Focuses on energy changes in chemical processes. Explains internal energy, enthalpy, work, heat, Hess’s law, spontaneity, Gibbs free energy, and basics of entropy. It teaches how to predict whether a reaction will occur.
Chapter 6: Equilibrium
Covers physical and chemical equilibrium. Explains the law of mass action, equilibrium constant, Le Chatelier’s principle, ionic equilibrium, acids and bases (Arrhenius, Bronsted, Lewis concepts), pH scale, buffer solutions, and solubility product.
Chapter 7: Redox Reactions
Introduces oxidation and reduction reactions. Explains oxidation number, balancing redox reactions (ion-electron and oxidation number method), and applications of redox processes in daily life.
Chapter 8: Organic Chemistry – Some Basic Principles and Techniques
Explains the basics of organic chemistry—structure of organic compounds, nomenclature, electronic displacements (inductive, resonance, hyperconjugation), and reaction mechanisms. It also introduces methods of purification like distillation, crystallization, and chromatography.
Chapter 9: Hydrocarbons
Deals with alkanes, alkenes, alkynes, and aromatic hydrocarbons. Explains their structure, nomenclature, properties, and reactions. Covers isomerism and special properties of benzene with mechanisms of important reactions.
Chapter 10: The Redox & Environmental Chemistry (Optional in some syllabi)
Some syllabi include an introduction to environmental chemistry—air, water, soil pollution, green chemistry, and strategies to reduce pollution.
