Preparation of alcohols from alkenes involves the electrophilic attack on alkene carbon atom. Explain its mechanism.
Preparation of alcohols from alkene by the hydration of alkenes in presence of sulphuric acid. This addition reaction takes place in accordance with Markownikoff's rule.
Mechanism: The mechanism of the reaction involves the following three steps.
Step 1 Protonation of alkene to form carbocation by electrophilic attack of .
Step 2 Attack of water moleoule to the secondary carbocation
Step 3 Loss of the hydragen from the protonated alcohol.
