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

Options

  1. AA carbonyl compound with a hydrogen atom on its alpha-carbon never equilibrates with its corresponding enol.
  2. BA carbonyl compound with a hydrogen atom on its alpha-carbon rapidly equilibrates with its corresponding enol
  3. CA carbonyl compound with a hydrogen atom on its alpha-carbon rapidly equilibrates with its corresponding enol
  4. DA carbonyl compound with a hydrogen atom on its alpha-carbon rapidly equilibrates with its corresponding enol

Correct answer

D. A carbonyl compound with a hydrogen atom on its alpha-carbon rapidly equilibrates with its corresponding enol

Step-by-step 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: Keto-enol tautomerism
