Enolate anion

Enolate anion

An enolate anion is an anion derived by loss of a proton from the alpha carbon of a carbonyl group; it is the anion of an enol.

For instance, a base abstracts one proton from acetone to form enolate anion.

The enolate anion is stabilized by resonance and therefore the alpha hydrogen is acidic.
