NEET 2016 Chemistry Tautomerism MCQ Question
Choose the CORRECT statement regarding a carbonyl compound with a hydrogen atom on its alpha-carbon atom.
A carbonyl compound with a hydrogen atom on its alpha-carbon rapidly equilibrates with its corresponding enol and this process is known as carbonylation.
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.
A carbonyl compound with a hydrogen atom on its alpha-carbon never equilibrates with its corresponding enol.
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.
Correct Answer
Detailed Explanation
Keto-enol tautomerism is a chemical equilibrium between a keto form (a ketone or an aldehyde) and an enol (an alcohol). It involves the migration of a hydrogen atom and a switch of a single bond and adjacent double bond.
