"Addition of water"  an alkene in the presence of a catalytic amount of strong acid leads to formation of alcohols (hydroxy‐alkanes). This reaction proceeds via a standard carbocation mechanism and following  Markovnikov rule.Second carbon of the original double‐bonded carbons becomes a carbocation.


May b I'm not sure this answer.i will try my best.

This reaction proceeds via a standard carbocation mechanism and follows the Markovnikov rule. The mechanism for the addition of water to ethene follows.
1. The hydrogen ion is attracted to the π bond, which breaks to form a σ bond with one of the double‐ bonded carbons. The second carbon of the original double‐bonded carbons becomes a carbocation.
2.An acid‐base reaction occurs between the water molecule and the carbocation, forming an oxonium ion.
3. The oxonium ion stabilizes by losing a hydrogen ion, with the resulting formation of an alcohol.

Alkenes undergo an addition reaction with water in the presence of a catalyst to form an alcohol. This type of addition reaction is called hydration. The water is added directly to the carbon – carbon double bond. The hydration of alkenes can be undertaken by various methods.
