WebElectrophilic hydration is the reverse dehydration of alcohols and has practical application in making alcohols for fuels and reagents for other reactions. The basic reaction under certain temperatures (given below) is the following: The phrase “electrophilic” literally means “electron loving” (whereas “nucleophilic” means “nucleus loving”).

WebThe two alcohol molecules involved in the reaction play two roles—one alcohol molecule acts as a substrate while the other acts as a nucleophile. The reaction follows an S N 2 mechanism. The dehydration of secondary and tertiary alcohols to get corresponding ethers is unsuccessful as alkenes are formed easily in these reactions. WebThis is a ketone, this is acetone. And so adding water to acetone gives us this as our product for our hydrate. Except, we know that ketones are not as reactive as aldehydes, and so this time the equilibrium is to the left. It favors …

WebMechanism of Hydration of Alkenes The following steps are involved in the reaction: Step 1: Alkene undergoes protonation to form carbocation by electrophilic attack of H 3 O +. Step 2: Water, being a nucleophile, attacks on the carbocation. Step 3: Deprotonation occurs to form an alcohol. Oxymercuration/ Demercuration
