Dear vivek,

In part, tautomers are "isomers that are rapidly interconverted." Frequently, however, the less stable of two tautomers is the important on terms of a compound's ability to exhibit a particular sort of chemical reactivity.

The most important type of tautomerism in organic chemistry are keto-enol tautomers. Primarily because of the much greater strength of a carbonyl double bond as compared with an alkene double bond, the keto form is usualy the more stable of the two.

All the best.
