Question

Which among the following polyhalogen compounds is used in carbylamine reaction?

• A. $CHCl_3$
• B. $CH_2Cl_2$
• C. $CCl_4$
• D. $CCl_2F_2$

Answer 1

Answer: (A)

$CHCl_3$

Answer 2

The carbylamine reaction involves the reaction of a primary amine with chloroform ($CHCl_3$) in the presence of a base (KOH) to form an isocyanide. Out of the given compounds, only $CHCl_3$ is used in this reaction.

Carbylamine reaction: Primary amine + $CHCl_3$ + Base → Isocyanide.

Only $CHCl_3$ is suitable among the options.
