Question

The correct statement regarding a carbonyl compound with a hydrogen atom on its alpha carbon, is:

Options

A.

A carbonyl compound with a hydrogen atom on its alpha-carbon never equilibrates with its correspondingenol.

B.

carbonyl compound with a hydrogen atom on its alpha-carbon rapidly equilibrates with its correspondingenol and this process is known as aldehyde-ketone equilibration.

C.

A carbonyl compound with a hydrogen atom on its alpha-carbon rapidly equilibrates with its correspondingenol and this process is known as carbonylation.

D.

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

Solution
