Answer

  1. The catalyst in the given reaction isH2SO4.
  2. The catalyst in the given reaction is I-.

Step by step solution

01

Step-by-Step SolutionStep 1: Catalyst

The substance used to increase the rate of a reaction without itself undergoing a chemical reaction is named a catalyst.

02

Catalyst in reaction a

Reaction a

The H2Omolecule is participating in the chemical reaction as it gets dissociated into H and OH and gets added to the carbon atoms of the alkene.

Therefore, the species that do not participate in the reaction is H2SO4and hence H2SO4acts as the catalyst.

03

Catalyst in reaction b

Reaction b

In the given reaction, it is clearly observable that the hydroxide ion OH-is involved in the reaction.

The OH-ion replaces Cl from CH3Cl.

Therefore, the catalyst in the given reaction isI-.
