Q. $CHCI_{3}$ and $KOH$ on heating with a compound from a bad smelling product, compound is
A) $C_{2}H_{5}CN$
B) $C_{2}H_{5}NC$
C) $C_{2}H_{5}OH$
D) $C_{2}H_{5}NH_{2}$
Explanation
(b)
This is carbylamine reaction which is used to distinguish 1${^\circ}$ amines from other amines. The reaction is given by 1${^\circ}$ amines only.
$C_{2}H_{5}NH_{2} + CHCI_{3} + 3KOH \rightarrow C_{2}H_{5}N\overset{=}{\rightarrow}C + 3KCI + 3H_{2}O$
$RNH_{2} + CHCI_{3} + 3KOH \rightarrow R - N\overset{=}{\rightarrow}C + 3KCI + 3H_{2}O$
1${^\circ}$amine chloroform isocyanide
(bad smelling)
