enantiomeric. Compare with diasteromer. Two molecules that are nonsuperimposable mirror images of each other. One enantiomer rotates plane-polarized light to the left; the other rotates it to the right. 
In chemistry, an enantiomer (ər {respell|ə|NAN|tee-ə-mər}; from the Greek ἐνάντιος, opposite, and μέρος, part or portion) is one of two stereoisomers that are mirror images of each other that are non-superposable (not identical), much as one`s left and right hands are the same except for opposite orientation. Organic compounds t....
One of a pair of molecular entities which are mirror images of each other and non-superimposable.
One of a pair of non-superimposable, mirror-image stereoisomers.
One of the two mirror-image forms of an optically active molecule.
Enantiomers are pairs of stereoisomers that are mirror images of one other
One of the two mirror-image forms of an optically active molecule.
