Concept explainers
(a)
To determine: The structures of the compounds with two of the groups on the stereocenter shown in Figure 5.5 interchanged.
Interpretation: The structures of the compounds with two of the groups on the stereocenter shown in Figure 5.5 interchanged are to be drawn.
Concept introduction: If two compounds have same molecular formual 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. Optical isomers are identified on the basis of their mirror images. Geometric isomers are also referred as cis-trans isomers.
(b)
To determine: The relationship of the new compound to the original compound.
Interpretation: The relationship of the new compound to the original compound is to be stated.
