Question

Which of the following reaction is an example of ammonolysis?

• A. ${\mathrm{C}}_6{\mathrm{H}}_5{\mathrm{CH}}_2\mathrm{CN}\to {\mathrm{C}}_6\mathrm{H}5\mathrm{CH}2{\mathrm{CH}}_2{\mathrm{NH}}_2$
• B. ${\mathrm{C}}_6{\mathrm{H}}_5\mathrm{COCl}+{\mathrm{C}}_6{\mathrm{H}}_5{\mathrm{NH}}_2\to {\mathrm{C}}_6{\mathrm{H}}_5{\mathrm{CONHC}}_6{\mathrm{H}}_5$
• C. ${\mathrm{C}}_6{\mathrm{H}}_5{\mathrm{CH}}_2\mathrm{Cl}+{\mathrm{NH}}_2\to {\mathrm{C}}_6{\mathrm{H}}_5{\mathrm{CH}}_2{\mathrm{NH}}_2$
• D. ${\mathrm{C}}_6{\mathrm{H}}_5{\mathrm{NH}}_2\to {\mathrm{C}}_6{\mathrm{H}}_5{{\mathrm{NH}}_3}^{+}{\mathrm{Cl}}^{-}$

Answer 1

The correct option is C

${\mathrm{C}}_6{\mathrm{H}}_5{\mathrm{CH}}_2\mathrm{Cl}+{\mathrm{NH}}_2\to {\mathrm{C}}_6{\mathrm{H}}_5{\mathrm{CH}}_2{\mathrm{NH}}_2$

C. ${\mathrm{C}}_6{\mathrm{H}}_5{\mathrm{CH}}_2\mathrm{Cl}+{\mathrm{NH}}_2\to {\mathrm{C}}_6{\mathrm{H}}_5{\mathrm{CH}}_2{\mathrm{NH}}_2$

Ammonolysis:

When an alkyl halide or benzyl halide reacts with an ethanolic solution of ammonia (${\mathrm{NH}}_3$), the halogen atom is replaced by an amino (${\mathrm{NH}}_2$) group, resulting in a nucleophilic substitution reaction. This process of breaking of the carbon-halogen bond is known as ammonolysis.

Hence, option C is the answer.
