How will you prepare alcohols from alkyl halides and alkenes ? Write chemical equations.

Text Solution

Verified by Experts

(i) Alkyl halides react with aqueous `KOH` to form alcohols. For example,
`underset("Ethyl chloride")(C_(2)H_(5)-Cl+KOH (aq)) rarr underset("Ethyl alcohol")(C_(2)H_(5)OH+KCl)`
(ii) Alkenes upon acidic hydration form alcohols. For example,
`underset("Propylene")(CH_(3)CH=CH_(2))+H_(2)O overset(H^(+))(rarr) underset("Isopropyl alcohol")(CH_(3)underset(OH)(CH)CH_(3))`
