Vedclass · Answer

(A) In electrophilic aromatic substitution,the orientation of the incoming group depends on the nature of the substituent already present on the benzene ring.Groups that are electron-withdrawing by inductive or resonance effects (deactivating groups) are meta-directing.Among the given options,$-COOH$ is an electron-withdrawing group due to the presence of the carbonyl group attached to the benzene ring,which makes it a meta-directing group.$-Cl$ is ortho/para-directing due to the resonance effect.$-NH_2$ and $-CH_3$ are ortho/para-directing due to their electron-donating nature.Therefore,the correct answer is $-COOH$.

When $C_6H_5Z$ undergoes electrophilic substitution,the major product obtained is the meta-isomer. Therefore,the group $Z$ is:
