Many kinds of enols are known. [1] Keto–enol tautomerism refers to a chemical equilibrium between a "keto" form (a carbonyl, named for the common ketone case) and an enol. The interconversion of the two forms involves the transfer of an alpha hydrogen atom and the reorganisation of bonding electrons. The keto and enol forms are tautomers of ...
The Boston Naming Test (BNT), introduced in 1983 by Edith Kaplan, Harold Goodglass and Sandra Weintraub, is a widely used neuropsychological assessment tool to measure confrontational word retrieval in individuals with aphasia or other language disturbance caused by stroke, Alzheimer's disease, or other dementing disorder.

The ferric chloride test is used to determine the presence of phenols in a given sample or compound (for instance natural phenols in a plant extract). Enols , hydroxamic acids , oximes, and sulfinic acids give positive results as well. [ 1 ]

They are the sulfur analogs of enols (hence the thio-prefix). Alkenes with a thiol group on both atoms of the double bond are called enedithiols. Deprotonated anions of thioenols are called thioenolates. These structures exhibit tautomerism to give thioketones or thioaldehydes, analogous to keto–enol tautomerism of carbonyl structures. [1]

The shortened term ynol typically refers to alkynols with the hydroxyl group affixed to one of the two carbon atoms composing the triple bond (C≡C−OH), the triple-bond analogues to enols. [1] Ynols can tautomerize to ketenes. The deprotonated anions of ynols are known as ynolates, the triple-bond analogues to enolates.
