Enantiomers is a term that refers to the two molecules that are mirror images of one another but demonstrate chirality of the inability to be superimposed on one another. socratic Subjects
Enantiomers of a compound with more than one stereocenter are also diastereomers of the other stereoisomers of that compound that are not their mirror image. Diastereomers have different physical properties (unlike enantiomers) and different chemical reactivity. Diastereoselectivity is the preference for the formation of one or more than one diastereomer over the other in an organic reaction.
