the R-(+) enantiomer of a certain compound has a specific rotation of +52. A mixture of this compound with its enantiomer has a has an observed rotation of -26. what is the %ee of this sample and which enantiomer is in excess? what is the ration of R:S in this mixture?
Part B Enantiomers If you had a racenic mixture of the two enantiomers mentioned in Part A, what would you expect the specific rotation to be for this mature and WH? Choose one answer from below. ANSWER The specific rolation would be 104.4 degrees because the oplical acdvily af each indvidust enantiomer would be 52.2 degrees The specifie rotation would be zero because the enantiomers would react with one another to create a solution that is not The speciic rotation...
