Please tell me the important topics of chemistry (Pradeep’s edition) class 11?
Also, tell me the marks carried by chemistry chapters?
The more weightage chapters include: “Chemical Bonding and Molecular Structure”
States of Matter: Gases, Liquids and solids
Chemical Thermodynamics
Equilibrium
Redox Reactions
Hydrogen
s -Block Elements
p -Block Elements
Individual important topics include:
Chemical Bonding and Molecular Structure
covalent character of ionic bond, valence bond theory, resonance, geometry of covalent molecules, VSEPR theory, concept of hybridization, involving s, p and d orbitals and shapes of some simple molecules
States of Matter: Gases, Liquids and Solids
Three states of matter, intermolecular interactions, types of bonding, melting and boiling points, role of gas laws in elucidating the concept of the molecule, Boyle’s law, Charles law, Gay Lussac’s law, Avogadro’s law, ideal behaviour, empirical derivation of gas equation, Avogadro’s number, ideal gas equation
Liquid State: vapour pressure, viscosity and surface tension
Unit cell in two dimensional and three dimensional lattices, calculation of density of unit cell, packing in solids, packing efficiency, voids, number of atoms per unit cell in a cubic unit cell
Chemical Thermodynamics
First law of thermodynamics -internal energy and enthalpy, heat capacity and specific heat, measurement of AU and AH, Hess’s law of constant heat summation, enthalpy of bond dissociation, Second law of Thermodynamics (brief introduction). Introduction of entropy as a state function, Gibb’s energy change for spontaneous and non- spontaneous processes,
Equilibrium
Le Chatelier’s principle, ionic equilibrium- ionization of acids and bases, strong and weak electrolytes, degree of ionization, ionization of poly basic acids, acid strength, concept of pH, Henderson Equation
Redox Reactions
Redox reactions, oxidation number, balancing redox reactions, in terms of loss and gain of electrons and change in oxidation number
Hydrogen
Preparation, properties and uses of hydrogen, hydrides-ionic covalent and interstitial; physical and chemical properties of water, heavy water, hydrogen peroxide -preparation, reactions and structure and use
s -Block Elements
Most of the topics are important. Leaving any topic would be a loss
p -Block Elements
All the Group 13, 14 and 15 elements are important
