The correct statement regarding a carbonyl compound with a hydrogen atom on its alpha carbon, is:
Options
- AA carbonyl compound with a hydrogen atom on its alpha-carbon never equilibrates with its corresponding enol.
- BA carbonyl compound with a hydrogen atom on its alpha-carbon rapidly equilibrates with its corresponding enol
- CA carbonyl compound with a hydrogen atom on its alpha-carbon rapidly equilibrates with its corresponding enol
- 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
