1 Constitutional isomers are compounds that have the same molecular formula and different connectivity. To determine whether two molecules are constitutional isomers, just count the number of each atom in both molecules and see how the atoms are arranged. 2 Geometric isomers- each of two or more compounds that differ from each other in the arrangement of groups with respect to a double bond, ring, or other rigid structure. 3 Optical isomers- each of two or more forms of a compound that have the same structure but are mirror images of each other and typically differ in optical activity. 4 Stereoisomers- each of two or more compounds differing only in the spatial arrangement of their atoms.
