प्रश्न
Preparation of alcohols from alkenes involves the electrophilic attack on alkene carbon atom. Explain its mechanism.
Advertisements
उत्तर
The mechanism of the reaction involves the following three steps:
Step 1: Protonation of alkene to form carbocation by the electrophilic attack of H3O+.
\[\ce{H2O + H+ -> H3O+}\]

Step 2: Nucleophilic attack of water on carbocation.

Step 3: Deprotonation to form an alcohol.
