Whether the Wolff-Kishner reduction and Clemmensen reduction should be carried out on a ketone or aldehyde that contains the nitrile group (R-C ≡ N ) is to be determined. Concept introduction: Nitrile (R-C ≡ N ) can be hydrolyzed to an amide under either acidic or basic condition. The Wolff-Kishner reduction is carried out in basic condition in water, and Clemmensen reduction is carried out in acidic condition in water.

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.
