tautomerism

Question

Keto-enol tautomerism involves migration of:

RankGuru · Accepted Answer

1. **Tautomerization**: A type of isomerism where isomers interconvert rapidly through the migration of a mobile atom (usually hydrogen).
2. **Mechanism**: In keto-enol tautomerism, a proton ($H^+$) moves from the $\alpha$-carbon to the carbonyl oxygen.
3. **Bond Shift**: Simultaneously, the $C=O$ double bond shifts to become a $C=C$ double bond.
4. **Relationship**: While keto form is usually more stable, the enol form can be significant in systems like acetylacetone due to intramolecular H-bonding.
