Ethanol

Vedclass · Answer

(A) Acid-catalysed hydration of alkenes follows Markovnikov's rule,where the hydroxyl group $(-OH)$ attaches to the more substituted carbon atom.$CH_2=CH_2 + H_2O \xrightarrow{H^+} CH_3CH_2OH$ (Ethanol).$CH_3CH=CH_2 + H_2O \xrightarrow{H^+} CH_3CH(OH)CH_3$ (Propan$-2-$ol).$CH_3CH_2CH=CH_2 + H_2O \xrightarrow{H^+} CH_3CH_2CH(OH)CH_3$ (Butan$-2-$ol).Methanol $(CH_3OH)$ cannot be prepared by this method as it requires at least two carbon atoms.Propan$-1-$ol and Butan$-1-$ol are primary alcohols that cannot be formed by direct hydration of simple alkenes due to Markovnikov's rule.Therefore,Ethanol is the correct answer.

Which of the following alcohols is prepared by acid-catalysed hydration of alkenes?
