Question
Chapter 5, Problem 5.60P
Interpretation Introduction
Interpretation:
The direction in which the given mixture will rotate the plane-polarized light is to be determined. The enantiomeric excess of the mixture is to be calculated.
Concept introduction:
The ability of a mixture of enantiomers to rotate the plane polarized light is governed by the percentage of the enantiomer which is in excess. If a given mixture is excess in the (+) enantiomer, then the rotation of the plane polarized light will be in the (+) direction.
If a mixture contains unequal amounts of the (+) and (-) enantiomers, it will be optically active. Such a type of mixture is considered as being a certain percentage racemic, and the remaining percentage is called the enantiomeric excess (ee).
