Chiral etymology
WebA chiral molecule is non-superimposable with its mirror image, and has a "handedness" (think of shoes, which specifically go with a right or left foot). An achiral molecule is superimposable with its mirror image and do not have "handedness" (think of a baseball bat, which can be used with either hand).. Created by Jay.

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 ...
