Which electrophilic aromatic substitution reaction is reversible? a. nitration b. alkylation c. alkanoylation d. sulfonation e. halogenation

D. Sulfonation

Explanation:

Electrophilic aromatic substitution -

The subsitution reaction , where the hydrogen atom of an aromatic ring is replaced by an external electrophile .

Sulfonation reaction -

The subsitution reaction , where the hydrogen atom of an aromatic ring ( benzene) is replaced by an sulfonyl group , is called an Sulfonation reaction .

The Sulfonation reaction is reversible in nature , because , heating of aqueous sulfuric acid with sulfonic acid , can lead to a reverse reaction , i.e. , desulfonation .
