WebChirality Centers. A chirality center (chiral center) is a type of stereocenter. A chirality center is defined as an atom holding a set of four different ligands (atoms or groups of atoms) in a spatial arrangement which is non-superposable on its mirror image. Chirality centers must be sp 3 hybridized, meaning that a chirality center can only ... WebThe chirality center can also be called the asymmetric center. We will use the term chirality center in this book. It is highly recommended that the molecular model set is used as a learning tool in this chapter. Assemble the model as shown above to understand the concept of chiral and chirality.
