Vedclass · Answer

(A) The starting material is $1$-fluoro-$4$-methoxybenzene. The methoxy group $(-OCH_3)$ is a strongly activating group and is ortho/para-directing,while the fluoro group $(-F)$ is a weakly deactivating group and is also ortho/para-directing.In this molecule,the $-OCH_3$ group is at position $1$ and the $-F$ group is at position $4$. The positions ortho to the $-OCH_3$ group are positions $2$ and $6$. The positions ortho to the $-F$ group are positions $3$ and $5$.Due to the stronger activating effect of the $-OCH_3$ group,the electrophilic substitution (nitration) will be directed primarily by the $-OCH_3$ group. The position ortho to $-OCH_3$ (position $2$) is also meta to the $-F$ group. The position ortho to $-F$ (position $3$) is meta to the $-OCH_3$ group.Since $-OCH_3$ is a much stronger activating group than $-F$,the nitration occurs predominantly at the position ortho to the $-OCH_3$ group. Thus,the major product is $1$-fluoro-$4$-methoxy-$2$-nitrobenzene.
