Concept explainers
(a)
To determine: All distinct stereoisomers for the given structure and the relationship between the isomers, any meso isomers and any mirror planes of symmetry.
Interpretation: All distinct stereoisomers for the given structure are to be drawn and the relationship between the isomers is to be shown. Any meso isomers present are to be labeled and mirror planes of symmetry are to be drawn if possible.
Concept introduction: If two compounds have same molecular formula, but the spatial arrangement of atoms is different, then they are known as stereoisomers. Stereoisomers are further divided into two categories: optical isomers and geometrical isomers. The two different forms in which a single chiral carbon can exist is referred as enantiomers. The class of diastereomers includes stereoisomers that are not enantiomers. They are not the mirror images of each other. There are two or more chiral centers, generally present in diastereoisomers.
