Concept explainers
(a)
Interpretation: The stereogenic centers in the given drug are to be located.
Concept introduction: A carbon atom that has four nonequivalent atoms or groups attached to it is known as chiral carbon atom. Chiral carbon centers are also called as asymmetric or stereogenic centers.
(b)
Interpretation: The stereogenic centers in the given drug are to be located.
