The D- and L- system is named after the Latin dexter and laevus, which translates to left and right. The assignment of D and L is used to distinguish between two molecules that relate to each other with respect to reflection; with one molecule being a mirror image of the other. These types of molecules are referred to as chiral ...

WebStereochemistry is an important aspect of Organic Chemistry and you must be able to draw structures which clearly indicate the stereochemical orientation of the various groups on a molecule. For any given compound there will be a right way and many wrong ways to indicate stereochemistry. WebChiral centers are the most common features within molecules that give rise to chirality. Stereoisomer: A molecule that possesses at least one chiral center (or center of chirality). Enantiomers: A type of stereoisomer that exists in mirror image forms. See Figure 1. Diastereomers: A type of stereoisomer that possesses more than one chiral center.
