Which of the following reagent is used to convert alkene to alcohol through hydration ?

Step-by-step solution

Hydration of alkenes to alcohols requires the addition of water across the carbon-carbon double bond. Since water is a weak acid, it cannot initiate the electrophilic addition reaction on its own. An acid catalyst is required to provide H ^+ ions, which attack the double bond to form a carbocation intermediate. Therefore, H ₂ O in the presence of a strong acid like H ₂ SO ₄ (dilute sulfuric acid) is used as the reagent for the hydration of alkenes to yield alcohols. Answer: H ₂ O in presence of H ₂ SO ₄
