Q. The compound obtained by heating a mixture of $1{^\circ}$ amine and chloroform with ethanolic potassium hydroxide is
A) An alkyl isocyanide
B) An alkyl isothiocyanate
C) An amide
D) An amide and nitro compound
Explanation
(a)
Primary amines on heating with chloroform and ethanolic KOH, give alkyl isocyanide. This reaction is called carbylamine reaction.
$R - NH_{2} + CHCI_{3} + 3KOH\overset{\mathrm{\Delta}}{\rightarrow}R - NC + 3KCI + 3H_{2}O$
