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

The correct statement regarding a carbonyl compound with a hydrogen atom on its alpha carbon, is:
  1. A carbonyl compound with a hydrogen atom on its alpha-carbon never equilibrates with its corresponding enol.
  2. 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.
  3. A carbonyl compound with a hydrogen atom on its alpha-carbon rapidly equilibrates with its corresponding enol and this process is known as carbonylation.
  4. 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.

Solution

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

The tautomeric structures are given below:
