Answer to Question #294340 in Organic Chemistry for Bhavani

Question

Explain the meta directing nature of NO2 group?

Answer 1

-NO2 group is an electron withdrawing group. ... As a result, the electron density at meta position is relatively higher than at the ortho and para position. So, electron deficient electrophile always attacks at meta position. Hence, nitro group is meta directing in electrophilic aromatic substitution reaction
