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 equlibration.

(2) a carbonyl compound with a hydrogen atom on its alpha-carbon rapidly eqilibrates with its corresponding enol and this process is known as carbonylation.

(3) a carbonyl compound with a hydrogen atom on its alpha-carbon rapidly eqilibrates 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
