WebIn geometry, a figure is chiral (and said to have chirality) if it is not identical to its mirror image, or, more precisely, if it cannot be mapped to its mirror image by rotations and translations alone. An object that is not chiral is said to be achiral..

Chiral objects don't have a plane of symmetry. An achiral object has a plane of symmetry or a rotation-reflection axis, i.e. reflection gives a rotated version. Optical isomers or enantiomers are stereoisomers which exhibit chirality.

WebA chiral molecule is an enantiomer of its mirror image. As well, a chiral molecule and its mirror image are enantiomers. Diasteriomers have multiple stereocenters, each diasteriomer also often has an enantiomer. You're thinking of Meso compounds where a Diasteriomer isn't chiral since it doesn't have an enantiomer. Some Diasteriomers are indeed ...
