WebAug 26, 2024 · Most chiral organic molecules have at least one carbon atom that is bonded to four different groups, as occurs in the bromochlorofluoromethane molecule shown in part (a) in Figure 24.7. 2. This carbon, often designated by an asterisk in structural drawings, is called a chiral center or asymmetric carbon atom. WebThis is why the molecules can exist in different stereoisomeric forms, and the orientation of the radical groups is what is only different between these enantiomers.
