`RCHO+NH_(2)NH_(2)toRCH=N-NH_(2)`
What sort of reaction is it-

A

electrophilic addition - elimination reaction

B

free radical addition - elimination reaction

C

electrophilic substitution - elimination reaction

D

nucleophilic addition - elimination reaction

Text Solution

Verified by Experts

The correct Answer is:
D
In the given reaction `overset(* *)(N)H_(2)overset(* *)(N)H_(2)` combines with the substrate as nucleophilic reagent and in the subsequent step 1 mol of `H_(2)O` is eliminated.
Hence, it is a nucpleophilic addition elimination reaction.
