Potential Isomerism: Asymmetric Carbons

➢ Chiral: Molecules containing a carbon atom attached to four different groups or atoms

➢ One chiral center: – Two enantiomers (enantiomorphs) – Non-superimposable mirror images – Optically active – Individual isomers: other properties the same ➢ Racemate: – Optically inactive – Some other properties differ (mp, solubility)
