Concept explainers
(a)
Interpretation:
Enatiomers for the given compound has to be drawn using perspective formula.
Concept Introduction:
Perspective formulas show the 3D array of atoms in which the solid wedges indicate bonds projecting above the plane of the drawing and wedge shaded with parallel line indicate bonds projecting below the plane of drawing.
Example:
Enantiomers: These are stereoisomers that are not superimposable mirror images of each other and the configurations at all stereo genic centers are exactly opposite.
Enantiomer can be drawn by replacing the wedge with a dash from the perspective formula of a compound.
Chiral center: A chiral center is defined as the tetrahedral carbon atom in an organic molecule that is connected to four non-identical groups/substituents. It is sometimes known as a stereo genic center.
An achiral carbon is a carbon having two or more identical groups around it.
(b)
