(a)
Interpretation: The mechanism of given reaction when it involves specific-acid catalysis and general-acid catalysis has to be drawn.
Concept introduction:
Catalyst: Substance which helps in increasing the rate of a particular reaction without getting consumed in the reaction.
Acid Catalyst: A catalyst which helps in increasing the rate of a particular reaction by the donation of a proton. There are two types of catalysis:
- Specific-acid catalysis: Proton is completely transferred before the slow step to the reactant in a reaction
- General-acid catalysis: Proton is completely transferred during the slow step to the reactant in a reaction
