Addition of ammonia derivatives: Aldehydes and ketones react with a number of ammonia derivatives \((H_2N—Z)\) in weakly acidic medium to form compounds containing carbon-nitrogen double bonds with the elimination of water molecule. The reaction is reversible and is catalyzed by acid. The equilibrium favours the product formation due to the rapid dehydration of the intermediate to form \(C=N—Z\).

Let us look at each of the options:
