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
