Topics That Appear Every Year

01Mole concept — stoichiometry calculations and limiting reagent
02Quantum numbers — all 4 numbers and electronic configuration
03Chemical bonding — VSEPR shapes and hybridisation
04Thermodynamics — Hess's law and Gibbs energy
05Equilibrium — Le Chatelier's principle and pH calculations
06Organic nomenclature — IUPAC rules for all functional groups
07Periodic trends — ionisation energy, electron affinity, atomic radius
08Redox reactions — balancing by half-reaction method

Study Strategy for 90+

1

Chemistry splits into 3 streams: Physical (numerical), Inorganic (theory), Organic (mechanisms)

2

Physical chemistry needs daily numericals — mole concept, pH, thermodynamics

3

Inorganic: periodic trends and chemical bonding are most important — revise daily

4

Organic: master nomenclature before attempting reaction mechanisms

5

Equilibrium is the hardest chapter — spend extra time on Le Chatelier's principle
