WebIn general, the number of stereoisomers of a molecule can be determined by calculating 2 n, where n = the number of chiral centers in the molecule. This holds true except in cases where the molecule has meso forms. WebA 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 have single bonds. [5] islamic frame redWebWell, this carbon number two is a chirality center, and carbon number three is a chirality center, so two chirality centers, so I use the formula of two to the n, where n is the number of chirality centers so I would expect two squared or four possible stereoisomers for this molecule. So you could draw four different stereoisomers for this ... key lime pie florida city
