By the action of alcoholic caustic potash on chloroform and aniline, a bad-smelling substance is formed. The substance is

Options

  1. ANitrobenzene
  2. BPhenyl isocyanide
  3. CPhenyl cyanide
  4. DPhenyl isocyanate

Correct answer

B. Phenyl isocyanide

Step-by-step solution

Action of alcoholic caustic potash on chloroform and aniline forms a bad-smelling compound phenyl isocyanide. C 6 H 5 N H 2 + C H C l 3 + 3 K O H alcohol → C 6 H 5 N C + 3 K C l + 3 H 2 O This reaction is called carbylamine reaction and it is actually the test of primary amines.
