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 ... WebJul 20, 2016 · chiral: [adjective] of or relating to a molecule that is not superimposable on its mirror image.
