Concept explainers
(a)
Interpretation: The number of stereogenic centers in the given compound is to be predicted. The maximum number of possible stereoisomers is to be predicted.
Concept introduction: An atom bearing four different atoms or groups which produces stereoisomers on interchange of any two groups are stereogenic centers.
(b)
Interpretation: Both enantiomers of mandelic acid is to be drawn and stereogenic center is to be labeled as
Concept introduction: The stereogenic centers with
(c)
Interpretation: The
Concept introduction: Enantiomeric excess is the excess of major enantiomer over the minor enantiomer. Enantiomeric excess is equivalent to the optical purity. Enantiomeric excess is the fraction of observed rotation of the mixture to specific rotation of the pure enantiomer
(d)
Interpretation: Enantiomeric excess of the given solution is to be calculated. The percentage of each enantiomer present is to be calculated.
Concept introduction: Enantiomeric excess is the excess of major enantiomer over the minor enantiomer. Enantiomeric excess is equivalent to the optical purity. Enantiomeric excess is the fraction of observed rotation of the mixture to specific rotation of the pure enantiomer.

- You came across an article debating the use of Prevacid® vs. Nexium®. While both drugs have the same therapeutic effect, one is sold as a racemate and the other is sold as a single enantiomer. Previous medications such as Thalidomide and Advair® have sparked a debate about the safety of drugs sold as a racemate. Why are drugs sometimes sold as a racemate?arrow_forwardFor the following molecules: a. How many stereogenic centers are present? b. How many stereoisomers are possible for these molecules?arrow_forwardWhat is the lupac Name for thisarrow_forward
