Physical Chemistry (Structure & Equilibrium)

Focus: Numericals & Laws

  1. Mole Concept: Molarity, Molality, and Limiting Reagent numericals.
  2. Atomic Models: Bohr’s Model postulates and limitations.
  3. Quantum Numbers: Significance of \(n, l, m, s\) and Pauli’s Exclusion Principle.
  4. Electronic Config: Rules (Aufbau, Hund’s) and exceptions (Cr, Cu). Must Do
  5. Thermodynamics: First Law (\(\Delta U = q + w\)) and Hessian Law of Heat Summation.
  6. Enthalpy: \(\Delta H\) vs \(\Delta U\) relationship: \(\Delta H = \Delta U + \Delta n_g RT\).
  7. Entropy & Gibbs Energy: Spontaneity conditions (\(\Delta G < 0\)).
  8. Equilibrium Constant: \(K_p\) vs \(K_c\) relation:
    \[K_p = K_c(RT)^{\Delta n}\]
  9. Le Chatelier’s Principle: Effect of Temp, Pressure, and Concentration.
  10. Ionic Equilibrium: Buffer Solutions and pH calculation. Numerical
  11. Solubility Product: \(K_{sp}\) and precipitation condition.

Inorganic Chemistry (Bonding & Trends)

Focus: Structures & Concepts

  1. Periodic Trends: Atomic Radius, Ionization Enthalpy, and Electronegativity variations.
  2. VSEPR Theory: Shapes of molecules (\(NH_3, H_2O, PCl_5, SF_6\)). Diagram
  3. Hybridization: \(sp, sp^2, sp^3\) concepts and examples.
  4. MOT (Molecular Orbital Theory): Energy level diagrams for \(O_2\) and \(N_2\). Graph
  5. Bond Order: Calculation and Magnetic behavior (Paramagnetic/Diamagnetic).
  6. Dipole Moment: Resultant vectors (Why \(NF_3\) < \(NH_3\)).
  7. Hydrogen Bond: Inter vs Intra molecular H-bonding examples.
  8. Redox Reactions: Balancing by Ion-electron method.
  9. Oxidation Number: Calculation rules and exceptions (e.g., \(CrO_5\)).

Organic Chemistry (GOC & Hydrocarbons)

The Foundation for Class 12

  1. IUPAC Naming: Rules for Polyfunctional groups.
  2. Electronic Effects: Inductive, Electromeric, Resonance, and Hyperconjugation.
  3. Isomerism: Chain, Position, Functional, and Metamerism.
  4. Carbocations: Stability Order (\(3^\circ > 2^\circ > 1^\circ\)) and Rearrangement.
  5. Purification: Distillation, Chromatography, and Crystallization principles.
  6. Alkanes: Wurtz Reaction and Kolbe’s Electrolysis.
  7. Alkenes: Markovnikov’s vs Anti-Markovnikov’s Rule (Peroxide effect). Mechanism
  8. Ozonolysis: Predicting products of alkene cleavage.
  9. Alkynes: Acidic character and polymerization (Benzene formation).
  10. Benzene: Aromaticity (Huckel’s Rule) and Resonance energy.
  11. Friedel-Crafts: Alkylation and Acylation of Benzene.
  12. Directing Groups: Ortho/Para (activators) vs Meta (deactivators) directors.

Asterisk Classes: Study Strategy

  • GOC is Key: Do not skip General Organic Chemistry (GOC). The concepts of Resonance and Inductive Effect are the alphabet of Class 12 Organic Chemistry.
  • Bonding: Master the Molecular Orbital Theory (MOT) diagrams. A question on Bond Order or Magnetic nature of \(O_2/N_2\) is 100% guaranteed.
  • Numericals: In Equilibrium and Thermodynamics, pay attention to the units of \(R\) (Gas Constant) and Temperature (Kelvin).
