Enol meaning in chemistry
WebEnols are aldehydes or ketone isomers in which one alpha hydrogen has been removed and placed on the carbonyl group’s oxygen atom. The molecule is called an ene/ol, i.e., an enol, because it has a C=C and an -OH group. enols can only be created from carbonyl components with alpha hydrogens. http://www.chem.ucla.edu/~harding/IGOC/E/enal.html

In organic chemistry, alkenols (shortened to enols) are a type of reactive structure or intermediate in organic chemistry that is represented as an alkene (olefin) with a hydroxyl group attached to one end of the alkene double bond (C=C−OH). The terms enol and alkenol are portmanteaus deriving from "-ene"/"alkene" … See more Organic esters, ketones, and aldehydes with an α-hydrogen (C−H bond adjacent to the carbonyl group) often form enols.
