B) an alkyl isothiocyanate
C) an amide
D) an amide and nitro compound
Correct Answer: A
Solution :
Primary amines on heating with chloroform and ethanolic\[KOH,\]give alkyl isocyanide. This reaction is called carbylamine reaction. \[\underset{{{1}^{o}}\text{ }amine}{\mathop{R-N{{H}_{2}}}}\,+CHC{{l}_{3}}+\underset{(alcohol)}{\mathop{3KOH}}\,\xrightarrow[{}]{\Delta }\underset{alkyl\text{ }isocyanide}{\mathop{R-NC}}\,\] \[+3KCl+3{{H}_{2}}O\]
