CH 320M Chapter Notes - Chapter 3: Meso Compound, Stereoisomerism, Enantiomer
Document Summary
3. 4 acyclic molecules with two or more stereocenters. When two or more stereocenters exist in a molecule, multiple stereoisomers are possible. Molecules with one chiral center two stereoisomers (one pair of enantiomers) are possible. For a molecule with n chiral centers, the maximum number of stereoisomers possible is. Two stereoisomers will be enantiomers if all of the chiral centers present are reversed; will be diastereomer if only some of chiral centers are reversed. Enantiomers have identical physical and chemical properties in an achiral environment. Diastereomers have different physical and chemical properties, even in achiral environments. 3. 5 cyclic molecules with two or more chiral centers. 3. 7 optical activity - how chirality is detected in the laboratory. One property that differs between enantiomers is their effect on the rotation of the plane of polarized light: each member of a pair rotates the plane of polarized light in opposite directions.
