Question 1
What is the % ee of a sample of carvone that exhibits a specific rotation of −40, given that the specific rotation of (
R)-carvone is −61?
◦ 50%
◦ 20%
◦ 66%
◦ 61%
◦ 33%
Question 2
If a sample of carvone gives a specific rotation of −60 and the specific rotation of (
R)-carvone is −61, does the unknown sample primarily have the
R or
S absolute configuration?
◦
S◦
R◦ It is a racemic mixture.
◦ This cannot be determined from the information given
