2. “Describe …” — Sequence main steps or features without unnecessary opinion. Reward: accuracy + completeness.
3. “Evaluate …” — Present advantages and limitations; conclude with a justified judgement. Reward: balance + evidence.

Practise these on the Carboxylic Acids subtopic page and Carboxylic Acids quiz.

Common mistakes students make
