An attempt at synthesizing a certain optically-active compound resulted in a mixture of its enantiomers. The mixture had an observed specific rotation of +11.5°+11.5°. If it is known that the specific rotation of the ?R enantiomer is −38.0°−38.0°, determine the percentage of each isomer in the mixture.

Question
An attempt at synthesizing a certain optically-active compound resulted in a mixture of its enantiomers. The mixture had an observed specific rotation of +11.5°+11.5°. If it is known that the specific rotation of the ?R enantiomer is −38.0°−38.0°, determine the percentage of each isomer in the mixture.
Expert Solution
Step 1
We have given,
The specific rotation of the mixture= +11.5°
The specific rotation of the R enantiomer= -38.0°
Percentage of each isomer in the mixture=?
