The substituent attached to the benzene ring that act as Ring deactivator is.
Correct answer: A. NO2
- A. NO2
- B. COOH
- C. Cl
- D. NH3
Explanation
A ring deactivator is a substituent that reduces the reactivity of the benzene ring towards electrophilic substitution reactions. NO2 (nitro group) is a strong ring deactivator because it:- Withdraws electrons from the ring through resonance- Has a negative inductive effect, reducing the electron density in the ring
