 On heating an aliphatic primary amine with chloroform and ethanolic  potassium hydroxide , the organic compound formed is


A) an alkanol

B) an alkanediol

C) an alkyl cyanide

D) an alkyl isocyanide

Answer:

Option D

Explanation:

This reaction is an example of carbylamine reaction which includes conversion of amine to isocyanide.

          $R-\ddot{N}H_{2}+CHCl_{3}$  $\xrightarrow[{KOH}]{C_{2}H_{5}OH}$   $R-N^{+}\equiv C^{-}:$

                                                                                          Alkyl isocyanide

Note:   This reaction include  rearrangement reaction of nitrene in which migration of alkyl group from carbon to nitrogen takes place.
