A reaction of a carbonyl compound with one of the following reagents involves nucleophilic addition followed by the elimination of water. The reagents is 

  • a Grignard reagent

  • hydrazine in presence of feebly acidic solution

  • hydrocyanic acid

  • sodium hydrogen sulphite

Solution

C.

hydrocyanic acid

Reaction of carbonyl compounds with ammonia derivatives give addition product followed by the elimination reaction. Slightly acidic medium generate a nucleophilic centre for the attack of weak base like ammonia derivatives.
