Imagine a Hypothetical Reaction to Make a Chiral Molecule That $[ \alpha ] _ { \mathrm { D } } ^ { 20 }$

Essay

Imagine a hypothetical reaction to make a chiral molecule that gives the desired product (the R enantiomer, which has a specific rotation of −95^o mL g⁻¹ dm⁻¹) in 68% EE. What percentage of the product is R, and what percentage is S? (Show your work.)
$[ \alpha ] _ { \mathrm { D } } ^ { 20 }$
