Problems and exercisesThe Result of an Experiment
1. Enantiomeric excess
The 2-octanol obtained contains 94% of the S enantiomer and 6% of the R. Calculate its enantiomeric excess and the expected specific rotation, given that pure (S)-2-octanol has +9.5°.
2. The kinetics
Doubling the concentration of HO− or that of the halide doubles the rate of alcohol formation. What does this tell us?
3. Optically inactive alkenes
Why are the alkenes formed optically inactive?
4. The equation
Write the equation of the major substitution reaction, indicating the configuration of reactant and product.
