The correct statement regrarding a carbonyl compound with a hydrogen atom on the its alpha-carbon is:

Options

A. 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. a carbonyl compound with a hydrogen atom on its alpha-carbon never equilibrates with its corresponding enol.
C. a carbonyl compound with a hydrogen atom on its corresponding enol and this process is known as aldehyde-ketone equilibrations.
D. a carbonyl compound with a hydrogen atom on its alpha-carbon rapidly equibrates with its corresponding enole and this process is known as carbonyl cation.

Answer

A

Explanation

It is know that basic need for the existance of Keto-enol tautomers is the presence of at least one hydrogen atom at adjacent `sp^(3)` carbon of carbonyl carbon as it involves `1,3`-migration
