Diastenco-Isomer:- Pair of optically active isomen of a molecule with two or more different Chimal Carbon) atom) which are neithere identical non minnon image of each other. e.g. 2,3-dibromo Pentane Bre Bre Let us Consider Structure I and III. The upper half of the molecule arce identical while the lower half represent minnore image of each other. Such a Pair of optically active isomer which are not Mirror image of each other, are Called diastereo-isomer Property :- 1. They show different physical Property Buch as melting Point, density, boiling Point, refractive index etc. 2. They Cau be easily Deparated from each other with the help of fractional distillation. 3. They differ in rate of reaction with certain substance. Enantiomerr Diastereo-isomert 1. These are stereo isomer that have mirrore image relationship. 1. These arce Stereoisomen that do not have mirror image relationship. 2. They have Dimilar Pugsical Properties. 2. They have differcent Physical Properties. 3. They can't be peparated by fractimal distillation method. 3. They Cau be separated by fractional distillatim method.
