Which of the following amine will give the carbylamine test ? 1. Aniline (C ₆ H ₅ NH ₂ ) 2. C ₆ H ₅ NHCH ₃ 3. C ₆ H ₅ N(CH ₃ ) ₂ 4. C ₆ H ₅ NHC ₂ H ₅

Answer: 1. Aniline (C ₆ H ₅ NH ₂ ) The carbylamine test (heating with CHCl₃ and alcoholic KOH to give a foul-smelling isocyanide) is given only by primary amines, which have an -NH₂ group. Aniline C₆H₅NH₂ is primary. C₆H₅NHCH₃ and C₆H₅NHC₂H₅ are secondary, and C₆H₅N(CH₃)₂ is tertiary, so they do not respond. Answer: option (1).

Answer: 1. Aniline (C\(_6\)H\(_5\)NH\(_2\))

The carbylamine test (heating with \(\mathrm{CHCl_3}\) and alcoholic KOH to give a foul-smelling isocyanide) is given only by primary amines, which have an \(-\mathrm{NH_2}\) group.

Aniline \(\mathrm{C_6H_5NH_2}\) is primary. \(\mathrm{C_6H_5NHCH_3}\) and \(\mathrm{C_6H_5NHC_2H_5}\) are secondary, and \(\mathrm{C_6H_5N(CH_3)_2}\) is tertiary, so they do not respond. Answer: option (1).
