WebAcid catalyzed dehydration of alcohols occurs when the hydroxyl group of the alcohol is protonated to form an alkyloxonium ion (3). This ion loses a water molecule thus forming a carbocation (3). The water whose conjugate base is H 3 O + removes a hydrogen from the carbocation thus forming an alkene (3). WebHowever, in the presence of sulphuric acid, alcohols get protonated and then lose water to form alkene. C H 3 − C H 2 − O H C H 2 = C H 2 + H 2 O Solve any question of The p …
