The enantiomers are mirror images of each other and cannot be superimposed. The presence of the chiral centre in the molecule allows two enantiomers to exist which are stereoisomers as the molecules have the same atoms bonded to each …

A fully equivalent definition, rooted in molecular symmetry, is that a species is chiral if it does not have any improper axes of rotation.. An improper rotation is a rotation of the species (say 90° clockwise in the plane of the page), followed by a reflection perpendicular to the axis of rotation (in this case, the page).
