How do we distinguish between homomers and diastereomers?
Homomers | Diastereomers |
1. Homomers are a pair of compounds that have the same configuration at all of their stereocenters. | 1. Diastereomers are the compounds that have the same molecular formula and the sequences of bonded atoms but which are non-superimposable, non-mirror images |
2. Two homomers may differ in their confirmation. | 2. They may or may not be optical isomers. |
3. They are not optical isomers, but they appeared to be different when we rotate the molecule, to confuse us. | 3. Two diastereomers may show similar, but not identical chemical properties. |
4. For example, 1. 2. | 4. For example, 1. 2. |
