The following four structures are naturally occurring optically active compounds. Star (*) the asymmetric carbon atoms in these structures.
Interpretation: The asymmetric carbon atoms in the given structures are to be marked by star.
Concept introduction: A chiral carbon atom is attached to four different atoms or group of atoms and shows a tetrahedral geometry. The mirror image of a chiral compound is non-super imposable. The two different forms in which a single chiral carbon can exist are referred as enantiomers. The number of enantiomers of a molecule depends on the number of chiral centers.
To determine: The asymmetric carbon atoms in the given structures marked by star.
Answer to Problem 5.25SP
