JEE · NEET Previous Year Question
The correct statement regarding a carbonyl compound with a hydrogen atom on its alpha-carbon, is :
Topic: NEET PYQ
Answer: A. Full step-by-step solution below.
- Aa carbonyl compound with a hydrogen atom on its alpha-carbon rapidly equilibrates with its corresponding enol and this processes is known as keto-enol tautomerism .
- Ba carbonyl compound with a hydrogen atom on its alpha-carbon never equilibrates with its corresponding enol.
- Ca 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.
- Da carbonyl compound with a hydrogen atom on its alpha-carbon rapidly equilibrates with its corresponding enol and this process is known a carbonylation.
Correct answer: A
Solution
(a) It is known that basic need for the existance of Keto-enol tautomers is the presence of at least one hydrogen atom at adjacent sp3 carbon of carbonyl carbon.More Carboxylic Acids & Derivatives PYQs
