Answer

${CH}_{3} {CH}_{2} {CH}_{2} {Br+NaNH}_{2} {→CH}_{3} {CH}_{2} {CH=NH}_{2} +NaBr Eliminationreaction {CH}_{3} {CH}_{2} {CH}_{2} {Br+NaNH}_{2} {→CH}_{3} {CH}_{2} {CH}_{2} {NH}_{2} +NaBr Substitutionreaction$

Step by step solution

SN2 reaction

It is a nucleophilic substitution reaction in which an old bond is broken and a new bond is formed. Both processes occur simultaneously. Hence, it’s a single-step reaction.

Two reacting species are involved in the rate-determining steps.

${CH}_{3} {CH}_{2} {CH}_{2} {Br+NaNH}_{2} {→CH}_{3} {CH}_{2} {CH}_{2} {NH}_{2} +NaBr Substitutionreaction$

E2 reaction

It is a nucleophilic elimination reaction in which old bond is broken and new bond is formed. Both the processes occur simultaneously and no intermediate is formed.

Here, carbon hydrogen or halogen bond breaks to form new double bond. Hence, it’s a single step reaction.

${CH}_{3} {CH}_{2} {CH}_{2} {Br+NaNH}_{2} {→CH}_{3} {CH}_{2} {CH=NH}_{2} +NaBr Eliminationreaction$
