WebStereochemistry focuses on stereoisomers. In stereochemistry, stereoisomerism, or spatial isomerism, is a form of isomerism in which molecules have the same molecular formula and sequence of bonded atoms (constitution), but differ in the three-dimensional orientations of their atoms in space. [1] [2] This contrasts with structural isomers ... WebOptical isomers have identical physical properties (except for polarised light) and identical chemical properties unless reacting with other optical isomers, when the orientation of the two molecules could have a bearing on the final result, for example in biological systems.
