Ans. Alcohols can be prepared from alkenes through a process called hydration, which involves the addition of water to the double bond of the alkene. This reaction is typically catalyzed by an acid, such as sulfuric acid (H2SO4), which provides a proton for the addition reaction. The general equation for the hydration of alkenes is:
Alkene + Water → Alcohol
For example, the hydration of propene (C3H6) yields propanol (C3H7OH).
