Enantiomer | Diastereomer |
1. Optical isomers having the same magnitude but different sign of optical rotation. | Differ in the magnitude of optical rotation. |
2. They have configuration with non-super impossible object mirror image relationship. | They are never mirror images. |
3. Enantiomers are identical in all properties except the sign of optical rotation. | Diastereomers differ in all physical properties. |
4. Separation of enantiomers is a tedious process. | Separation from the other pairs of enantiomers is easy. |
