Concept explainers
(a)
Interpretation:
Relationship between two given Fischer projections by means of stereoisomerism (identical or enantiomers) should be determined.
and
Concept Introduction:
Identical molecules are the ones with no isomers, neither constitutional isomers nor stereoisomers. Identical molecules have the same structural arrangement of atoms and the same three-dimensional arrangement.
Isomers are the molecules with the same formula but either with different structural connectivity (constitutional isomers) or different three-dimensional arrangement (stereoisomers).
A tetrahedral carbon atom bonded to four different groups is called a chiral center. A Molecule having at least one chiral center is a chiral molecule. When the mirror images of a chiral molecule are not superimposable, those mirror images become stereoisomers called enantiomers.
Fischer Projection is a method of drawing 3-D structures of organic molecules using cross formula. In this method, all non-terminal bonds are depicted as horizontal or vertical lines.
In the Fischer projection, horizontal bonds represent groups coming forward (drawn as wedges) and vertical bonds represent groups going backward (drawn as dashed wedges).
