WebIn 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" and the "-ol" suffix ... WebThis intermediate is stabilized by resonance; in particular, the negative charge can be delocalized into the ortho/para electron-withdrawing group (in this example, an ortho nitro group). The aromatic system is destroyed on forming the anion, and the carbon at the reaction site changes from planar (sp 2 bonds) to tetrahedral (sp 3 bonds).
