Study Notes
Nomenclature of Optical Isomers
- The DL system of nomenclature was developed by Fischer and Mosanott around 1900
- The DL system is used for naming optical active compounds
- The DL system is commonly used in sugar chemistry and optically active polyhydric carbonyl compounds
- The DL system is a relative nomenclature because it is based on the configuration of all molecules
