Concept explainers
(a)
Interpretation:
The three-dimensional representation for the enantiomers of each compound should be drawn.
Concept Introduction:
Enantiomers are the stereoisomers that are non-superimposable mirror images. In the three-dimensional representation of the compound, substituents are attached with dash and wedge bonds here, dash bonds (dashed lines) represent the group is attached from below the plane and wedge bond (solid lines) represent the group is attached from top of the plane.
(b)
Interpretation:
The three-dimensional representation for the enantiomers of each compound should be drawn.
