Question
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
Solution
The correct order of the steps in the sulfonation of benzene is: Proton Transfer: Nucleophilic Attack: Proton Transfer.
Here's a step-by-step breakdown:
-
Proton Transfer: The first step in the sulfonation of benzene is the protonation of the sulfuric acid. This is a proton transfer step where a proton from sulfuric acid is transferred to the benzene ring.
-
Nucleophilic Attack: The next step is a nucleophilic attack, where the benzene ring acts as a nucleophile and attacks the protonated sulfuric acid. This results in the formation of a sigma complex.
-
Proton Transfer: The final step is another proton transfer. This is where a proton is transferred from the sigma complex to a water molecule, resulting in the formation of the final product, benzene sulfonic acid, and regenerating the sulfuric acid catalyst.
