The specific rotation of (S)-carvone (at +20°C) is +61. A chemist
prepared a mixture of (R)-carvone and its enantiomer, and this mixture had an observed
rotation of −55°.
(a) What is the specific rotation of (R)-carvone at 20°C? (b) Calculate the % ee of this
mixture.
(c) What percentage of the mixture is (S)-carvone?
