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. WebCHFClBr is therefore a chiral molecule that exists in the form of a pair of stereoisomers that are mirror images of each other. As a rule, any tetrahedral atom that carries four …

WebChirality is a property of a molecule that results from its structure. Optical activity is a macroscopic property of a collection of these molecules that arises from the way they interact with light.

WebThe number of stereoisomers a molecule has can be determined by the number of chiral carbons it has. Stereoisomers include both enantiomers and diastereomers. Diastereomers , like enantiomers, share the same molecular formula and are non-superposable onto each other however, they are not mirror images of each other.
