Question

Meta director group is (A) - NH2 (B) - Cl (C) - NO2 (D) - OH​

Answer 1

Explanation:

Since NO2 is an electron withdrawing group, a glance at the resonance structures shows that the positive charge becomes concentrated at the ortho-para positions. Thus these positions are deactivated towards electrophilic aromatic substitution. Hence, NO2 is a meta-director, as we all learned in organic chemistry.
