The correct statement regarding a carbonyl compound with a hydrogen atom on its alpha-carbon, is
A
a carbonyl compound with a hydrogen atom on its alpha-carbon rapidly equilibrates with its corresponding enol and this process is known as aldehyde-ketone equilibration.
B
a carbonyl compound with a hydrogen atom on its alpha-carbon rapidly equilibrates with its corresponding enol and this process is known as carbonylation.
C
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.
D
a carbonyl compound with a hydrogen atom on its alpha-carbon never equilibrates with its corresponding enol.
Explanation
$\alpha$-H allows equilibrium with the enol form.
Detailed Solution
Keto-enol tautomerism: the keto form $-CH-C(=O)-$ equilibrates with the enol form $-C=C(OH)-$ by shift of the $\alpha$-hydrogen.
