The reaction,\[{{R}_{2}}C=NN{{H}_{2}}\xrightarrow{{{C}_{2}}{{H}_{5}}ONa}{{R}_{2}}C{{H}_{2}}+{{N}_{2}}\]  is called

A)  Clemmensen reduction

B)  Hunsdiecker reaction

C)  Tischenko reaction

D)  Wolff-Kishner reduction

Correct Answer: D

Solution :

                                                                                  Carbonyl compounds give alkane, on reaction with a mixture of hydrazine and \[{{C}_{2}}{{H}_{5}}ONa\] in the presence of ethylene glycol.    This  reaction is called Wolff-Kishner     reduction.
