WebAsymmetric carbon. An asymmetric carbon atom (chiral carbon) is a carbon atom that is attached to four different types of atoms or groups of atoms. [1] [2] Le Bel-van't Hoff rule states that the number of stereoisomers of an organic compound is 2 n, where n represents the number of asymmetric carbon atoms (unless there is an internal plane of ... WebWhen the central carbon is sp3 carbon and bonded with four different groups (represented by four different colors in the model), the molecule is chiral. The central carbon is called the chirality center (or asymmetric center). A molecule with one chirality center must be chiral. The chirality center can also be called the asymmetric center.

Because of the tetrahedral geometry of saturated carbon and the associated three-dimensional properties, molecules can have chirality as one stereochemical feature. Any object is chiral if it is different (nonsuperimposable) than its mirror image.
