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.
