Stereochemistry Models.

These notes accompany the lectures on stereochemistry delivered by Prof. Matt Fuchter. Selecting any given molecule will expose a 3D model in the bottom right of the window. This model can be oriented appropriately to help you analyze how the Cahn-Ingold-Prelog (CIP) notation has been derived for it. The stereochemical label is assigned automatically using the latest rules for doing so implemented in the display program used here (JSmol). Three programs available on the teaching computers can also be used to check stereochemical assignments, ChemDraw, ChemDoodle and Gaussview. You can also build your own models, convert them to 3D and assign the stereochemistry at the following page: https://chemapps.stolaf.edu/jmol/jsmol/cip.htm

These notes can be viewed on both regular desktop/laptop computers and tablet/phone devices (ensure you have JavaScript enabled) and can be accessed using the DOI: doi.org/dbjn. A definitive declaration of the CIP rules as of 2018 can be found at DOI: 10.1021/acs.jcim.8b00324 with a definitive set of tests here.
