Interpretation Introduction

Interpretation:

From the given information, the configuration of naproxen should be determined.

Concept Introduction:

Enantiomeric excess:

The equal amount of isomers in the mixture is called racemic mixture and it has 0 specific rotation so it is optically inactive value.

If a mixture contains unequal mixture of isomers means it can be optically active but the specific rotation value can varied by which enantiomer is present more than other isomer.

The excess of one isomer than other isomer in the mixture is known as enantiomeric excess (ee %), it is given by

ee%observed specific rotationspecific rotation of the pure enantiomer×100
