Question

Which of the following compound reacts with chloroform and a base to form phenyl isocyanide?

• A. Phenol
• B. Aniline
• C. Benzene
• D. Nitro benzene

Answer 1

Answer: (B)

Aniline

Answer 2

We know that

$\underset{\text{Aniline}}{C_{6}H_{5}NH_{2}} + \underset{\text{Chloroform}}{CHCl_{3}} + 3KOH \rightarrow \underset{\text{phenyl isocyanide}}{C_{6}H_{5}NC + 3KCl + 3H_{2}O}$

Thus in this reaction phenyl isocyanide is produced. this is called carbylamine reaction.
