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. WebTautomeric shift is an intramolecular proton shift that changes the bonding structure of the molecule. Tautomeric shift is an intramolecular electron shift that changes the bonding structure of the molecule. How may it lead to a mutation? It allows hydrogen bonding of normally noncomplementary bases.
