WebEnolization. Organic esters, ketones, and aldehydes with an α-hydrogen (C−H bond adjacent to the carbonyl group) often form enols.The reaction involves migration of a … WebThe name enol comes from the fact that we have a double bond in the molecule, so that's where the EN part comes in, and we also have an alcohol. You can see the OH over here so that's where the OL comes in. This is the enol form and then over here this is the keto form.

WebMay 22, 2024 · Tautomerization is a shift of the hydroxyl hydrogen to carbon 2 of the alkene, and viceversa. This means that it is an equilibrium process which is either acid or base catalyzed. In the acid-catalyzed tautomerization, the alkene acts as a base and a proton from the acid is added to the p-bond with formation of the most stable carbocation.
