- In chemistry,
tautomers (/ˈtɔːtəmər/) are
structural isomers (constitutional isomers) of
chemical compounds that
readily interconvert. The

Examples of keto-enol
tautomerism In
organic chemistry,
enols are a type of

- It
exists in
equilibrium with a
tautomer CH3−C(=O)−CH=C(−OH)−CH3. The
mixture is a
colorless liquid.
These tautomers interconvert so

tautomerism.
Although the
triol tautomer may have
aromatic character, the keto form predominates...

exists a keto-enol
tautomerism with its enol
tautomer 4-hydroxypyridine. In solution, the keto
tautomer is favoured, and the enol
tautomer only
becomes important...

- H−C≡N+−O−. It is an
isomer of
isocyanic acid (H−N=C=O) and of its
elusive tautomer,
cyanic acid (H−O−C≡N), and also of
isofulminic acid (H−O−N+≡C−). Fulminate...

tautomer. Keto–enol
tautomerism is
