Presence of a nitro group in a benzene ring

1. deactivates the ring towards nucleophilic substitution
2. activates the ring towards electrophilic substitution
3. renders the ring basic
4. deactivates the ring towards electrophilic substitution

Answer

From the resonating structures of nitrobenzene, it can be seen that the nitro-group withdraws electrons from the ring and hence it deactivates the benzene ring for further electrophilic substitution.

The correct option is D.
