Preparation of alcohols from alkenes involves the electrophilic attack on alkene carbon atom. Explain its mechanism.

Answer :

Preparation of alcohols from alkenes involves the electrophilic attack on alkene carbon atom. The mechanism of this reaction involves the following three steps:

Step 1) Protonation of alkene and formation of carbocation



Here, carbocation formation takes place by the electrophilic attack of H30+ on alkene carbon atom and water molecule is released.


STEP 2) Nucleophilic attack of water



Step 3) Deprotonation occurs and an alcohol is formed. H30+ is released.
