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...

You have a sample (Sample X) which is a mixture of +/- Carvone. The solution was made by dissolving 4.50 g of the sample in enough methanol to bring the volume of solution to 10,0 ml. Some of the solution is placed in a 100 cm polarimeter cell and its optical rotation is measured at 25°C using light of the sodium D line wavelength (589.6 nm). The observed rotation is...
