MCQ
Presence of a nitro group in a benzene ring:
  • deactivates the ring towards electrophilic substitution.
  • B
    activates the ring towards electrophilic substitution.
  • C
    renders the ring basic.
  • D
    deactivates the ring towards nucleophilic substitution.

Answer

Correct option: A.
deactivates the ring towards electrophilic substitution.
(a) deactivates the ring towards electrophilic substitution.
Explanation: This is because the Nitro is an electron-withdrawing group, it pulls the electron density from the ring towards itself thereby decreasing the electron density in the ring and deactivating the ring towards attack by the electrophile.
