Question: Which of the following reaction is an example of ammonolysis?
$\mathrm{C}_{6} \mathrm{H}_{5} \mathrm{COCl}+\mathrm{C}_{6} \mathrm{H}_{5} \mathrm{NH}_{2} \longrightarrow \mathrm{C}_{6} \mathrm{H}_{5} \mathrm{CONHC}_{6} \mathrm{H}_{5}$
$\mathrm{C}_{6} \mathrm{H}_{5} \mathrm{CH}_{2} \mathrm{CN} \stackrel{[\mathrm{H}]}{\longrightarrow} \mathrm{C}_{6} \mathrm{H}_{5} \mathrm{CH}_{2} \mathrm{CH}_{2} \mathrm{NH}_{2}$
$\mathrm{C}_{6} \mathrm{H}_{5} \mathrm{NH}_{2} \stackrel{\mathrm{HCl}}{\longrightarrow} \mathrm{C}_{6} \mathrm{H}_{5} \stackrel{+}{\mathrm{NH}}_{3} \mathrm{Cl}^{-}$
$\mathrm{C}_{6} \mathrm{H}_{5} \mathrm{CH}_{2} \mathrm{Cl}+\mathrm{NH}_{3} \longrightarrow \mathrm{C}_{6} \mathrm{H}_{5} \mathrm{CH}_{2} \mathrm{NH}_{2}$
Correct Option: , 4
Solution:
The process of cleavage of the $\mathrm{C}-\mathrm{X}$ bond by Ammonia molecule is known as ammonolysis.
$\mathrm{Ex}: \mathrm{R}-\mathrm{CH}_{2}-\mathrm{Cl}+\ddot{\mathrm{NH}_{3}} \longrightarrow \mathrm{R}-\mathrm{CH}_{2}-\mathrm{NH}_{2}$
