Procedure B. 1. Build two models of 1, 2-dimethyleyclopentane. The two methy can be on the same face or opposite faces of the ring. No matter how t molecule is twisted, they cannot be superimposed on each other. These compounds are stereoisomers of each other. 2. When two groups are present, the prefix cis (same face) or trans (opposite face) can be used in IUPAC nomenclature to specify which stereoisomer is being considered. For drawings, a solid wedged line in...
