Tardigrade Admin · Accepted Answer

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. Geometrical and optical isomerism is the class of stereoisomerism.
