Which of These Is a Keto-Enol Tautomeric Pair?
Keto-enol tautomerism is a type of chemical equilibrium in which a keto (carbonyl) form of a molecule reversibly interconverts with an enol (hydroxyl) form. This process is often facilitated by the presence of a hydrogen bond between the carbonyl oxygen and the hydroxyl hydrogen. Keto-enol tautomerism is a common phenomenon in organic chemistry, and it…
