Presence of a nitro group in a benzene ring

Question

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

Tardigrade Admin · Accepted Answer

- NO2 group shows - M effect, so withdraws the electron density from the ring and hence deactivate the ring towards electrophilic aromatic substitution. Hence, (4) is correct.

Q. Presence of a nitro group in a benzene ring

activates the ring towards electrophilic substitution

renders the ring basic

deactivates the ring towards nucleophilic substitution

deactivates the ring towards electrophilic substitution

$- N O_{2}$ group shows - M effect, so withdraws the electron density from the ring and hence deactivate the ring towards electrophilic aromatic substitution.
Hence, (4) is correct.
