Organic Chemistry – Some Basic Principles Part 1

Stereoisomerism involve those isomers which contain same ligands in their co-ordination spheres but differ in the arrangement of those ligands in space. Stereo-isomerism is of two type geometrical isomerism ligands occupy different positions around the central metal atom or ion.
NOTE : In optical isomerism isomers have same formula but differ in their ability to rotate directions of the plane of polarized light.
