Question

Presence of a nitro group in a benzene ring (A) renders the ring basic (B) deactivates the ring towards nucleophilic substitution (C) deactivates the ring towards electrophilic substitution (D) activates the ring towards electrophilic substitution

Tardigrade Admin · Accepted Answer

Presence of a nitro group in a benzene ring deactivates the ring towards electrophilic substitution preferably to ortho and para positions. This is clear from the following resonatic structure
