How would an ammonium group affect on benzene ring for subsequent reactions?
Correct answer: B. Deactivates the benzene ring towards electrophilic aromatic substitution
- A. Activates the benzene ring towards electrophilic aromatic substitution
- B. Deactivates the benzene ring towards electrophilic aromatic substitution
- C. Has no effect on the reactivity of the benzene ring
- D. Makes the benzene ring more reactive towards nucleophilic aromatic substitution
Explanation
he -NH₃⁺ group is a strongly electron-withdrawing, deactivating group.It reduces the ring's reactivity and directs substituents to the meta-position in electrophilic aromatic substitution reactions.

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.
