WHAT ARE ENANTIOMERS ?? PLEASE EXPLAIN WITH EXAMPES.

Enantiomers are stereoisomers of same compounds which are chiral molecules  that are non-superinposable mirror images of one another. The chiral molecules which consists of one or more stereocenters can be enantiomers.

 

For superimposability, there should be symmetry as in the case of meso-tataric acid, where one half the molecule rotates clockwise, while the other half rotates anticlockwise. Hence the net optical rotation is zero. Due to this internal compansation, meso- tartaric acid is optically inactive. The (+)tartaic acid and     (-)tartaric acid are enatiomers of eachother as they are non- superimposable mirror images of eachother.
