Vedclass · Answer

(A) The starting material is $1-$chloro$-3-$methoxybenzene. The $-OCH_3$ group is an ortho/para directing group,and the $-Cl$ group is also an ortho/para directing group. The $-OCH_3$ group is a stronger activating group than the $-Cl$ group,so the electrophilic substitution (nitration) is directed by the $-OCH_3$ group. The para position relative to $-OCH_3$ is occupied by the $-Cl$ group,so the nitration occurs at the ortho position relative to $-OCH_3$. Between the two ortho positions,the position para to the $-Cl$ group is less sterically hindered. Therefore,the major product is $1-$chloro$-4-$methoxy$-2-$nitrobenzene.

The major product of the following reaction is:
