Interpretation:
The enol structure of the compound
Concept introduction:
Ketone also exists in two forms which are commonly known as keto-enol tautomerism. Tautomers are isomers which differ only in the position of the protons and electrons of the double bond of the electronegative atom in the compound. 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.
