Enol

In <a href="/facts/Organic_chemistry/djxhxaNg">organic chemistry</a>, enols are a type of <a href="/facts/Functional_group/GXkSPsjM">functional group</a> or <a href="/facts/Chemical_intermediate/BjD9HAHt">intermediate</a> in <a href="/facts/Organic_chemistry/djxhxaNg">organic chemistry</a> containing a group with the formula C=C(OH) (R = many substituents). The term enol is an abbreviation of alkenol, a <a href="/facts/Portmanteau/d124JEbz">portmanteau</a> deriving from "-ene"/"alkene" and the "-ol". Many kinds of enols are known.
Keto–enol tautomerism refers to a <a href="/facts/Chemical_equilibrium/y8ToYXHp">chemical equilibrium</a> between a "keto" form (a <a href="/facts/Carbonyl/KJ71bo3X">carbonyl</a>, named for the common <a href="/facts/Ketone/BqQXpLo4">ketone</a> case) and an enol. The interconversion of the two forms involves the transfer of an alpha hydrogen atom and the reorganisation of bonding <a href="/facts/Electron/L0KBo5cW">electrons</a>. The keto and enol forms are <a href="/facts/Tautomerism/ucdXGP9C">tautomers</a> of each other.
