The correct statement regarding a carbonyl compound with a hydrogen atom on its $\alpha$-carbon is

  • A
    a carbonyl compound with a hydrogen atom on its $\alpha$-carbon never equilibrates with its corresponding enol.
  • B
    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.
  • C
    a carbonyl compound with a hydrogen atom on its $\alpha$-carbon rapidly equilibrates with its corresponding enol and this process is known as carbonylation.
  • D
    a carbonyl compound with a hydrogen atom on its $\alpha$-carbon equilibrates with its corresponding enol and this process is known as keto-enol tautomerism.
