Vedclass · Answer

(B) Meta-directing groups are electron-withdrawing groups that decrease the electron density of the benzene ring,particularly at the ortho and para positions,thereby directing the incoming electrophile to the meta position.In the given options,the set $-NO_2, -CHO, -SO_3H, -COR$ consists entirely of electron-withdrawing groups that are meta-directing.$-NH_2, -NHR, -OCH_3$ and $-NHCOCH_3$ are ortho/para-directing groups due to their electron-donating resonance effect.

Which of the following sets of functional groups contains only meta-directing groups?
