Chirality and stereochemistry

WebAbout this unit. Just like how your left foot doesn't quite fit your right shoe, molecules also can have properties that depend on their handedness! This property is called chirality. We will go over what makes a molecule chiral, stereoisomers, assigning configurations using the R,S system, optical activity and Fischer projections. WebStereochemistry – Viktor Meyer (1848–97) used the term in 1878 to describe the study of stereoisomers. In 1848, Louis Pasteur demonstrated that tartaric acid has optical activity, which is dependent on molecular symmetry, and in 1874, Jacobus H. van’t Hoff and Joseph-Achille Le Bel (1847–1930) independently demonstrated that a molecule with a carbon …
