Question

Propose a mechanism for the following reaction:

Short answer

The reaction mechanism is an acid hydrolysis reaction and it is given below.

Step-by-step solution

Step 1:Definition of hydration reaction

The addition of water to a molecule is called hydration reaction, so we can say that an alkene is hydratedin the presence of water and acid as only water is not a good electrophile to do addition reaction with alkene.

Stability of carbocation

That reaction will be hydrated rapidly which forms a stable carbocation in the transition state. The stability of carbocation depends on the hyperconjugation and the degree of carbocation formed.

The series of carbocation according to their stability is,

3°>2°>1°.
