Mechanism for the tautomerization process that occurs under acidic conditions has to be drawn. Concept Introduction: Keto-enol tautomerization occurs when a hydroxyl group is present next to a double bond in presence of acid or base. Due to this the ketone will have few amount of enol also. The quantity of ketone and enol is determined only by equilibrium. Acid catalyzed tautomerization: Compounds that are ketone can undergo keto-enol tautomerization in presence of acid. Tautomers are not same as resonance structures. The chemical properties of tautomers will be different. A general mechanism of keto-enol tautomerization that occur in acidic condition can be given as, First step is the formation of carbocation. Second step is the formation of double bond between oxygen and carbon atom. The water acts as a base and abstracts a proton to form the final keto compound.

Question

Definition Definition Organic compounds that have a carbonyl group, C = O, as their functional group. The carbonyl group in ketones is placed somewhere in the middle of the molecular structure, which means, the C=O is attached to two alkyl groups or benzene rings. Just like all other homologous series, the naming of ketones is done using a common suffix “-one”. The general molecular formula is C n H 2n O. Functional group of a ketone
