Alkyl cyanides undergo Stephen redyction to produce

A

Aldehyde

B

Secondary amine

C

Primary amine

D

Amide

Text Solution

Verified by Experts

The correct Answer is:
A
When a solution of alkyl cyanides in ether is reduced with stannous chloride and hydrochloric acid at room temperature, imine hydrochloride is obtained which on subsequent hydrolysis with boiling water, forms an aldehyde (stephen’s reduction.)
`R- C -= underset(2[H])overset(SnCl_(2)//HCl)rarr RCH = NH.HCl overset(H_(2)O)rarr RCHO + NH_(4)Cl`
