Enantiomer | Diastereomer |
(i) Optical isomers having the same magnitude but different sign of optical rotation. | Differ in the magnitude of optical rotation. |
(ii) They have configuration with non-super importable object mirror image relationship. | They are never mirror images. |
(iii) Enantiomers are identical in all properties except the sign of optical rotation. | Diasteromers differ in all physical properties. |
(iv) Separation of enantiomers is a tedious process. | Separation from the other pains of enantiomers is easy. |
