Question

2) Finish filling in the reagent table with all pertinent information. Mw m mol Density/Conc. Formula Mol.-eq. 11.0 Name Racemic Ibuprofen 0.24M KOH | (S)-(-)-a-Phenethylamine Amount 3.08 30 ml 0.48 3) Functionally, one of the salt diastereomers will precipitate out of solution, while the second would remain in solution. Explain why we do not need a full equivalent of the chiral resolving agent to achieve high yield during the separation step. 4) if you instead wanted to isolate (R)-(-)-Ibuprofen, could you simply use the same procedure with (R) (+)-a-Phenethylamine? Why or why not?

Questions 3 and 4 please
