Which of the following give a silver mirror with Tollens' reagent?

Abenzaldehyde
Bacetophenone
Cglucose
Dcyclohexanone

Answer: A, C

Tollens' reagent oxidises aldehydes, including the free aldehyde group of open-chain glucose in equilibrium, and silver ions are reduced to metallic silver. Simple ketones such as acetophenone and cyclohexanone are not oxidised. Options 1 and 3 are correct.
