Lecture Details

Freshman Organic Chemistry (CHEM 125)

Despite cautions from their conservative elders, young chemists like Paternó and vant Hoff began interpreting molecular graphs in terms of the arrangement of a molecules atoms in 3-dimensional space. Benzene was one such case, but still more significant was the prediction, based on puzzling isomerism involving "optical activity," that molecules could be "chiral," that is, right- or left-handed. Louis Pasteur effected the first artificial separation of racemic acid into tartaric acid and its mirror-image.
