Chapter 5, Problem 5.17YT

Interpretation Introduction

Interpretation:

Enantiomeric excess of the given solution that consists of $\text{3}0\%\text{ A }$ and $\text{7}0\%\text{ B}$ is to be determined.

Concept introduction:

If a mixture of enantiomers is not racemic, then it will be optically active, but it will not rotate light as much as one of the pure enantiomers does. Such a mixture can be viewed as being a certain percentage racemic, with the remaining percentage called the enantiomeric excess $\left(\text{ee}\right)$.
