Enol tautomer of the given compound has to be drawn. Concept Introduction: Keto-Enol tautomerization: The enol and keto are said to be tautomer, are constitutional isomers that rapidly interconvert via the migration of a proton. The interconversion between an enol and a ketone is called keto-enol tautomerization. Tautomerization is an equilibrium process, that the equilibrium will establish specific concentrations for both the enol and the ketone. Once the equilibrium is reached, the concentrations of ketone and enol can be measured. The tautomerization is catalyzed by even trace amounts of acid (or base). Tautomerism is the ability of a molecule to exist in more than one chemical form. Tautomers are formed by the migration of a hydrogen atom, accompanied by the switching of a single and neighboring double bond. The only difference in keto-enol tautomer is the location of hydrogen and double bond.

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
