WHAT DOES KETO-ENOL TAUTOMERISM MEAN IN ENGLISH?

Keto–enol tautomerism

In organic chemistry, keto–enol tautomerism refers to a chemical equilibrium between a keto form and an enol. The enol and keto forms are said to be tautomers of each other. The interconversion of the two forms involves the movement of an alpha hydrogen and the shifting of bonding electrons; hence, the isomerism qualifies as tautomerism. A compound containing a carbonyl group is normally in rapid equilibrium with an enol tautomer, which contains a pair of doubly bonded carbon atoms adjacent to a hydroxyl group, C=C-OH. The keto form predominates at equilibrium for most ketones. Nonetheless, the enol form is important for some reactions. The deprotonated intermediate in the interconversion of the two forms, referred to as an enolate anion, is important in carbonyl chemistry, in large part because it is a strong nucleophile. Normally, the keto–enol tautomerization chemical equilibrium is highly thermodynamically driven, and at room temperature the equilibrium heavily favors the formation of the keto form. A classic example for favoring the keto form can be seen in the equilibrium between vinyl alcohol and acetaldehyde.

Definition of keto-enol tautomerism in the English dictionary

The definition of keto-enol tautomerism in the dictionary is tautomerism in which the tautomers are an enol and a keto form. The change occurs by transfer of a hydrogen atom within the molecule.
