Question

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 never equilibrates with its corresponding enol.
• B. a carbonyl compound with a hydrogen atom on its $\alpha$-carbon rapidly equilibrates with its corresponding enol and this is known as aldehyde-ketone equilibration.
• C. a carbonyl compound with a hydrogen atom on its $\alpha$-carbon rapidly equilibrates with its corresponding enol and this process is known as carbonylation.
• D. a carbonyl compound with a hydrogen atom on its $\alpha$-carbon rapidly equilibrates with its its corresponding enol and its process is known as keto-enol tautomerism.

Answer 1

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

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


Hence, option (d) is correct.
