Question

Predict the reaction mechanism and product of the given reactions.

• A.
• B.
• C.
• D.

Answer 1

The correct option is A

The given substrate is a primary alkyl halide. They favour E2 and $S_{N}2$ reaction mechanism.

In (I), aq. $KOH$ act as strong nucleophile than base due to its smaller size. Thus, it undergoes $S_{N}2$ reaction to give alkyl alcohol.

In (II), KOt-Bu act as a strong base due to its larger size and it undergo E2 mechanism to give elimination product.
