Which of the following is not the characterstic of acid catalyzed hydration of alkenes?

Options

A. Reaction requires an acidic reagent.
B. The rate of reaction depends upon the concentration of both the alkene and the acidic reagent.
C. Where the reaction permits, it is accompanied by rearrangements.
D. The reaction is irreversible.

Answer

D

Explanation

The reaction is reversible as it is a typical acid-base equilibrium. The first step of the mechanism is the transfer of a proton to the alkene. Since water is not a strong acid and alkene is a weak base, hydration requires the presence of added strong acids for the reaction to occur.Since mechanism starts acid, the rate of reaction depends upon the concentration of both the alkene and the acidic reagent. The possible cause of rearrangement is the formation of carbocation intermediate.
