Q. No.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 rapidly equilibrates with its corresponding enol and this process is known as aldehyde-ketone equilibration.
2.
A carbonyl compound with a hydrogen atom on its alpha-carbon rapidly equilibrates with its corresponding enol and this process is known as carbonylation.
3.
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.
4.
A carbonyl compound with a hydrogen atom on its alpha-carbon never equilibrates with its corresponding enol.
