Which of the following substance on treatment with `NaNH_(2)` in liquid `NH_(3)` gives m-anisidine

A

o-Bromoanisole

B

m-Bromoanisole

C

p-Bromoanisole

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A, B
Nucleophilic substitution in the pressence of a strong base like `NaNH_(2)` takes place through elimination-addition or benzyne mechanism as explained below.

In this reaction both o-and m-bromonaisole give the same benzyne intermediate which on the addition of `NH_(3)` gives m-anisidine.
