Optical Activity - Specific Rotation & Enantiomeric Excess - Stereochemistry Youtube
By The Organic Chemistry Tutor
This organic chemistry video tutorial explains how to calculate the specific rotation of an enantiomer given the observed rotation, the pathlength, and the concentration of the solution. It discusses how to determine if a molecule will show optical activity based on its chirality. It also provides the formulas needed to calculate the optical purity and enantiomeric excess. Those formulas can be used to calculate the relative percentages of the R and S isomers.
