⚠️ 9701 Exam Notes / Pitfalls
Warning
- Same as for open-chain ketones:
attacks the carbonyl carbon. - Cyclohexanone gives 1-hydroxycyclohexane-1-carbonitrile — not chiral (ring is symmetrical about that carbon). An unsymmetrical ring ketone (e.g. 2-methylcyclohexanone) would give a chiral product.
- Must state trace
