7. If 10.6 mL of (+)-a-phenylethylamine (MM = 121.2, d = 0.940) are reacted
with 0.083 mol of (+)-tartaric acid, then:
a) how many grams of solid NaOH (MM = 40.0) are needed to convert the
(-)-amine diastereomeric salt into its free amine?
b) how many mL of a 2.5 M NAOH solution are needed to convert the
(-)-amine diastereomeric salt into its free amine?
8. Could a technique like TLC be used to separate enantiomers?
9. If the specific rotation of (2R,3R)-tartaric acid (see structure on page 7-1) is
+12.6°, then what is the specific rotation of (2R,3S)-tartaric acid?
