enolaisuus
Enolaisuus refers to a phenomenon in organic chemistry where a compound exists as a mixture of two or more tautomeric forms, specifically an enol form and its keto or aldehyde equivalent. This interconversion is known as tautomerism, and enolaisuus is a specific instance of this. The enol form contains a hydroxyl group attached to a carbon atom that is part of a carbon-carbon double bond, hence the "en-ol" nomenclature. The keto or aldehyde form has a carbonyl group (C=O).
The equilibrium between these tautomers is typically influenced by factors such as solvent, temperature, and pH.
The ability of a compound to exhibit enolaisuus is directly related to the presence of an alpha-hydrogen
