What type of reactive intermediate is formed in the reaction of an alkene with aqueous acid to give an alcohol?
Mariana [72]

Answer:

The intermediate is carbocation.

Explanation:

The reaction of alkene with an acid to give alcohol is an electrophilic addition reaction.

In electrophilic reaction, the alkene is being attacked by an alkene.

in case of aqueous acid reaction with alkene , the electrophile is [H⁺].

When the proton attacks the alkene it generates carbocation.

The carbocation generated is formed based on stability of carbocation.

The mechanism is shown in the figure.
