Q. Identify A and predict the type of reaction m-Bromoanisole ($3$-$BrC_6H_4OCH_3$) $\xrightarrow{NaNH_2}$ A
A) m-Anisidine ($3$-$H_2NC_6H_4OCH_3$) and substitution reaction
B) o-Anisidine ($2$-$H_2NC_6H_4OCH_3$) and elimination addition reaction
C) o-Bromoanisole ($2$-$BrC_6H_4OCH_3$) and cine substitution reaction
D) Anisole ($C_6H_5OCH_3$) and cine substitution reaction
Explanation
[Solution] $NaNH_2$ forms a benzyne (elimination-addition); $NH_2^-$ adds to give m-anisidine as the substitution product. Answer (1).
