Web4.2: Chiral and Achiral Molecules. Stereoisomers are isomers that differ in spatial arrangement of atoms, rather than order of atomic connectivity. One of their most interesting type of isomer is the mirror-image stereoisomers, a non-superimposable set of two molecules that are mirror image of one another. The existance of these molecules are ... 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.
