Chapter 5, Problem 40PP

Interpretation Introduction

Interpretation:

The enantiomeric excess (ee) should be identified for the given molecule by using its pair of enantiomeric structures.

Concept Introduction:

The enantiomeric excess (ee) is a measurement of purity for chiral substances. It reflects the degree to which a sample contains one enantiomer in greater amounts then the other.

The racemic mixture has an (ee) of $0\%$ while single completely pure enantiomer has an (ee) of $100\%$

For example a simple with $60\%$ of one enantiomer and $40\%$ of the other has an ee of $30\%(60-30=30\%)$
