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...
