Presence of a nitro group in a benzene ring

Options

  1. Aactivates the ring towards electrophilic substitution
  2. Brenders the ring basic
  3. Cdeactivates the ring towards nucleophilic substitution
  4. Ddeactivates the ring towards electrophilic substitution

Correct answer

D. deactivates the ring towards electrophilic substitution

Step-by-step solution

- NO ₂ group shows - M effect, so withdraws the electron density from the ring and hence deactivate the ring towards electrophilic aromatic substitution. Hence, (D) is correct.
