Concept explainers
(a)
Interpretation: All possible stereoisomers for the given compound are to be drawn and pairs of enantiomers and diastereomers are to be labeled.
Concept introduction: A disubstituted cycloalkane has two stereogenic centers. One should follow the given steps, while drawing all possible stereoisomers of a disubstituted cycloalkane. In first step, the cis and trans isomers of disubstituted cycloalkane is drawn. These isomers are diastereomers (stereoisomers that are not mirror images of each other). In second step, the mirror images of cis and trans isomers are to be drawn.
(b)
Interpretation: The all possible stereoisomers for given compound is to be drawn and pairs of enantiomers and diastereomers are to be labeled.
