$A$ carbonyl compound with a hydrogen atom on its $\alpha-$carbon rapidly equilibrates with its corresponding enol and this process is known as keto-enol tautomerism.

(B) Carbonyl compounds containing at least one $\alpha-$hydrogen atom exhibit tautomerism due to the acidic nature of the $\alpha-$hydrogen. The $\alpha-$hydrogen atom migrates to the carbonyl oxygen atom,resulting in an equilibrium between the keto form and the enol form. This phenomenon is specifically known as keto-enol tautomerism.
