Question

Which of the following amines gives carbylamine reaction?

$\left( C _{2} H _{5}\right)_{2} NH$

$\left( C _{2} H _{5}\right)_{3} N$

$CH _{3} NHC _{6} H _{5}$

$C _{2} H _{5} NH _{2}$

Answer

$C _{2} H _{5} NH _{2}$

Explanation

Solution

Aliphatic and aromatic primary amines when warmed with chloroform and an alcoholic solution of $KOH$ , form isocyanide or carbylamine. $\underset{\text { ethyl amine }}{ C _{2} H _{5} NH _{2}}+\underset{\text { chloroform }}{ CHCl _{3}}+3 KOH$ (alc.) $\xrightarrow{\text { Warm }} \underset{\text { ethyl isocyanide }}{ C_2 H _{5} NC }+3 KCl +3 H _{2} O$ Carbylamine reaction is a characteristic reaction of primary amines and can be used to distinguish primary amines from secondary and tertiary amines.
