Q64.Presence of a nitro group in a benzene ring (1) activates the ring towards electrophilic (2) renders the ring basic substitution (3) deactivates the ring towards nucleophilic (4) deactivates the ring towards electrophilic substitution substitution
What This Question Tests
This question assesses the understanding of the electronic effects of a nitro group on a benzene ring, specifically its strong deactivating effect towards electrophilic aromatic substitution due to electron withdrawal.
