Presence of a nitro group in a benzene ring. 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.

Deactivation of the benzene ring towards nucleophilic substitution:
Nucleophilic substitution reactions involve the attack of a nucleophile on an electrophilic center. In the case of a nitro group present on a benzene ring, it deactivates the ring towards nucleophilic substitution due to the strong electron-withdrawing nature of the nitro group.
Electron-withdrawing nature of the nitro group:
The nitro group is electron-withdrawing due to the presence of the electronegative nitrogen and oxygen atoms. This withdrawal of electron density from the benzene ring makes it less nucleophilic and less likely to undergo nucleophilic substitution reactions.
Effect on electrophilic substitution:
Although the nitro group deactivates the benzene ring towards nucleophilic substitution, it activates the ring towards electrophilic substitution reactions. This is because the nitro group is a meta-directing group, meaning that it directs incoming electrophiles to the meta position on the benzene ring.
Overall impact of the nitro group:
In conclusion, the presence of a nitro group in a benzene ring deactivates the ring towards nucleophilic substitution while activating it towards electrophilic substitution. This is due to the electron-withdrawing nature of the nitro group and its meta-directing effect on electrophilic substitution reactions.
