Vedclass · Answer

(B) The reaction of $o-$methoxychlorobenzene with $NaNH_2$ proceeds via the benzyne mechanism. In $o-$methoxychlorobenzene,the methoxy group $(-OCH_3)$ is an electron-donating group by resonance. When $NaNH_2$ is added,it abstracts the ortho-hydrogen to form a benzyne intermediate. The nucleophilic attack by the amide ion $(NH_2^-)$ on the benzyne intermediate is directed by the inductive effect of the methoxy group. The methoxy group exerts an electron-withdrawing inductive effect ($-I$ effect) at the ortho position,which makes the meta-carbon more electrophilic. Consequently,the nucleophile attacks the meta-position,leading to the formation of $m-$methoxyaniline as the major product.
