(a)
Interpretation: Enantiomeric excess of the given solution 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.
(b)
Interpretation: The percent of each enantiomer in the given solution 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.
(c)
Interpretation: The specific rotation
Concept introduction: Enantiomers are stereoisomers, which are non-superimposable images of each other. They have identical physical and chemical properties in symmetric environment. They rotate the plane-polarized light in equal amounts and in opposite directions.
(d)
Interpretation: Enantiomeric excess of the given solution 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.
