Solution
The mechanism of hydration of ethene to yield ethanol involves the following three steps:
Step 1: Protonation of alkene to form carbocation by electrophilic attack of H3O+.
\[\ce{H2O + H+ -> H3O+}\]

Step 2: Nucleophilic attack of water on carbocation.

Step 3: Deprotonation to form an alcohol.
