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 % )

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%)
