Question

For carbylamine reaction, we need hot alcoholic KOH and

• A. any primary amine and chloroform
• B. chloroform and silver powder
• C. a primary amine and an alkyl halide
• D. a monoalkylamine and trichloromethane

Answer 1

The correct option is A any primary amine and chloroform

In carbylamine reaction, primary amines on heating with chloroform in presence of alcoholic $KOH$ form isocyanides (or carbylamines) It is used to distinguish $1^{\circ }$ amines from $2^{\circ }$ and $3^{\circ }$ amines
$R-N{H}_2+CHC{l}_3+\underset{(alc.)}{3KOH}\to RNC+3KCl+3H_{2}O$
