Concept explainers
(a)
Interpretation:
The structure of the salmeterol should be drawn.
Concept Introduction:
(b)
Interpretation:
One chirality center in a salmeterol molecule should be identified.
Concept Introduction:
Chirality is the presence of an asymmetric carbon center in a molecule and a molecule which contains a chiral center cannot superimpose on its mirror image. To consider as chiral, molecule or object and its mirror image should not superimpose. To consider as achiral, molecule or object and its mirror image should be superimposed with each other.
In the above diagram, where C is the chiral center/ asymmetric carbon center.
A, B, D, E are four different functional groups.
(c)
Interpretation:
Enantiomers of salmeterol in three dimensions should be drawn.
Concept Introduction:
Mirror image of a molecule is a reflected duplicate of the molecule.
Enantiomers − the mirror image of the original molecule of a chiral molecule. These are stereoisomers.
