Question

Which of the following compounds will undergo carbylamine reactions?

• A. $\left(C H_{3} C H_{2}\right)_{2}NH$
• B. $\left(C H_{3}\right)_{2}NH$
• C. $C_{6}H_{5}NH_{2}$
• D. $\left(C H_{3}\right)_{3}N$

Answer 1

Answer: (C)

Carbylamine reaction is given by only primary amines (both aliphatic and aromatic). In this reation a primary amine reacts with chloroform in basic medium, to form a very bad smelling compound, called carbylamines
$C_{6}H_{5}NH_{2}+CHCl_{3}KOH \rightarrow C_{6}H_{5}NC+KCl+H_{2}O$
