WebVideo transcript. the RS system is used to describe the configuration of a chirality center. Down here we have a pair of enantiomers. On the left we have one compound, on the right we have its mirror image. We're going to assign an R orS to each of our enantiomers so let's start with step one. WebIf the sample only rotates plane-polarized light half as much as expected, the optical purity is 50%. Because R and S enantiomers have equal but opposite optical activity, it naturally …

Weboptical activity, but only half as much as if the sample were 100% of that enantiomer. These relationships could be expressed in formulae: Optical purity (op) = [ (optical rotation of pure compound) / (optical rotation of pure enantiomer) ] x 100% Enantiomeric excess (ee) = optical purity (that is, these numbers are always the same, schwinn beach cruiser mountain bikeWebMay 13, 2024 · The optical activity of a substance is measured by its specific rotation (or specific rotatory power)..
