Presence of a nitro group in a benzene ring.

A

Activates the ring towards electrophilic substitution

B

Renders the ring basic

C

Deativates the ring towards nucleophilic substitution

D

Deactivates the ring towards electrophilic substitution

Text Solution

Verified by Experts

The correct Answer is:
D
`-NO_2` group shows `-M` effect, so withdraws the electron density from the ring and hence deactivate the ring towards electrophilic aromatic substitution.
