The reaction, R- NH2 +CHCl3 + 3KOH xrightarrow textHeat R-NC +3KCl +3H2O is known as (A) Gabriel phthalimide synthesis (B) Hofmann reaction (C) Carbylamine reaction (D) Leibermann nitroso reaction

Tardigrade Admin · Accepted Answer

The given reaction is known as carbylamine reaction.

RN H_{2} + C H C l_{3} + 3 K O H Δ R - NC + 3 K Cl + 3 H_{2} O

It is a reaction for chemical test of primary amines.
In this reaction, the analyte is heated with alcohol, potassium hydroxide and chloroform. If primary amine is present, the isocyanide is formed.
