Concept explainers
(a)
Interpretation:
The percent of each enantiomer present for the given value needs to be calculated:
90% ee
Concept Introduction :
If one enantiomer dominates the other in a mixture of two, the excess of that enantiomer is then stated as a percentage of the total amount of that enantiomer. It also gives some information about the mixture's overall optical rotation.
(b)
Interpretation:
The percent of each enantiomer present for the given value needs to be calculated:
99%ee
Concept Introduction :
If one enantiomer dominates the other in a mixture of two, the excess of that enantiomer is then stated as a percentage of the total amount of that enantiomer. It also gives some information about the mixture's overall optical rotation.
(c)
Interpretation:
The percent of each enantiomer present for the given value needs to be calculated:
60%ee
Concept Introduction :
If one enantiomer dominates the other in a mixture of two, the excess of that enantiomer is then stated as a percentage of the total amount of that enantiomer. It also gives some information about the mixture's overall optical rotation.
