The sulfonation of benzene proceeds via a mechanism that involves three steps. Identify those three steps in their correct order.Select answer from the options belowProton Transfer: Nucleophilic Attack: Proton TransferNucleophilic Attack: Proton Transfer: Proton TransferProton Transfer: Proton Transfer: Nucleophilic AttackNucleophilic Attack: Rearrangement: Proton Transfer

Select the step that comes last in nucleophilic addition that is performed under acidic conditions.Select answer from the options belowThe anionic intermediate is protonated upon treatment with a mild proton source.The nucleophile attacks the protonated carbonyl group.The carbonyl group is protonated by the acid.
