The enol functional group is -CCOH, with a double bond between the two carbon atoms. Compounds containing this group are enols, and their conjugate bases--the -C=COH anion--are enolates. This arrangement is also present in phenols and some of the...

Enols (also known as alkenols) are alkenes with a hydroxyl group affixed to one of the carbon atoms composing the double bond. Enols and carbonyl compounds (such as ketones and aldehydes) are in fact isomers; this is called keto-enol...
