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

About Chemistry of Hydrocarbons
Hydrocarbons are studied through the structures and reactions of alkanes, alkenes, alkynes and aromatic compounds. Coverage includes free radical substitution in alkanes, electrophilic addition to carbon-carbon multiple bonds, benzene substitution, aromatic stability and the difference between addition reactions of alkenes and substitution reactions of benzene.
