Tautomerism is the phenomenon in which two structural isomers differing in the relative position of their atoms are spontaneously interconvertible and can exist in dynamicequilibrium.

Tautomers I and II are structural isomers that are related only by the shift of a hydrogen atom an one or more Pi bond.

The relation between the enol contents X, Y, Z should be

X gt Y gt Z

Z gt Y gt X

Y gt X gt Z

Y gt Z gt
