Tautomers are structural isomers (constitutional isomers) of chemical compounds that readily interconvert.
let us take an example of acteone,

these two are the tautomers of acetone that is keto and enol form.
The interconversion of the two forms involves the movement of an alpha hydrogen atom and the reorganisation of bonding electrons.
So the ketone and the enol form are called Tautomers.
hence the answer is Tautomers.
The ketone and the cnol for are called Conformers Diastereomers O Tautomers Enantiomers
