Question

$R-N{H}_{2}CHC{l}_3+3KOH\to A+3KCl+3H_{2}O.A$ is

• A. R - NC
• B. R - NH${}_2$
• C. R - NO${}_2$
• D. all

Answer 1

Answer: (A)

R - NC

$RN{H}_2+CHC{l}_3+3KOH\to \underset{isocyanide}{R-N\equiv C}+3KCl+3H_{2}O$
The reaction to used is distinguish between 1${}^o$, 2${}^o$ and 3${}^o$ amines. It is called Carbylamine reaction.
