WebThe maximum number of stereoisomers that can exist for a compound is 2n, where n is the number of chiral centers. Chiral centers are atoms, usually C, bonded to four different groups. Stereoisomers that differ in the direction they rotate a plane of polarized light are called optically active, or chiral, and their isomers are called enantiomers. coat of arms of senegal

"The chirality of a molecule is based on the molecular symmetry of its conformations. A conformation of a molecule is chiral if and only if it belongs to the Cn, Dn, T, O, I point groups (the chiral point groups). However, whether the molecule itself is considered to be chiral depends on whether its chiral conformations are persistent isomers that could be isolated as separated enantiomers, at least in principle, or the enantiomeric conformers rapidly interconvert at a given t… " - Chiral isomers
