Exam tips for Chemistry
- 01Organic mechanisms: arrow-pushing MUST show electron-pair movement, not atom movement.
- 02Equilibria: Le Chatelier's principle must be stated AND explained — not just listed.
- 03Spectroscopy: IR, NMR, and mass spec appear together — practise identifying compounds.
- 04Moles: always write a balanced equation before any mole calculation.
- 05E°cell = E°cathode − E°anode — use the data booklet; don't memorise electrode potentials.
