A stereogenic center (or stereocenter) is an atom such that swapping the positions of two ligands (connected groups) on that atom results in a molecule that is stereoisomeric to the original. For example, a common case is a tetrahedral carbon bonded to four distinct groups a, b, c, and d (Cabcd), where swapping any two groups (e.g., Cbacd) leads to a stereoisomer of the original… WebOther articles where chirality is discussed: isomerism: Enantiomers: …phenomenon of handedness, or “chirality,” is perhaps the most important phenomenon related to isomerism.
