Question

Discuss the purity of the final isolated enantiomer based on your data. Include the following in your discussion and compare to literature data. Physical appearance/color, specific rotation of the final isolated enantiomer, enantiomeric excess

a. The purity can be accurately assessed based on physical appearance.
b. Literature data is not essential for purity assessment.
c. Specific rotation is not an indicator of purity.
d. The purity cannot be determined without additional testing.

Answer 1

The purity of the final isolated enantiomer can be assessed through a combination of factors including physical appearance, literature data, specific rotation, and enantiomeric excess.

Step-by-step explanation:

The purity of the final isolated enantiomer can be assessed based on different factors. While physical appearance can provide some information, it is not enough to accurately determine purity. Literature data is essential for comparing the observed specific rotation of the final isolated enantiomer to known values. Specific rotation is indeed an indicator of purity, as enantiomers rotate plane-polarized light in opposite directions. Therefore, the enantiomeric excess, which measures the concentration of one enantiomer over the other, can also be used to assess the purity of the final isolated enantiomer.
