An “enol” is a type of organic compound that contains a hydroxyl group (-OH) attached to a carbon atom that is also double-bonded to another carbon atom (an alkene). In other words, enols are characterized by the presence of a C=C double bond and an adjacent alcohol (-OH) group. Enols are typically unstable and can interconvert to their corresponding keto forms (ketones or aldehydes) through a process called tautomerization.
