(a) Interpretation: The carbonyl compound in given pair that exhibits the higher percentage of the enol tautomer is to be identified. Concept introduction: Tautomers are isomers which differ only in the position of the hydrogen and electrons of the electronegative atom, generally oxygen. There is no change in the carbon skeleton of the compound. This phenomenon which involves simple proton transfer in an intramolecular fashion is known as tautomerism. The very common example of tautomerism is Keto-enol tautomerism. It can be acid or base catalysed. The very common example of tautomerism is Keto-enol tautomerism. It can be acid or base catalyzed. Formation of predominant product is determined by several factors.
