https://joechem.io/videos/18 for video on jOeCHEM and attached worksheet + solution (below video on jOeCHEM aka the link). In this video, we introduce the concept of evaluating whether a stereocenter (aka an atom that is attached to four different "groups") has an R or an S configuration. We talk about how to go about labeling a stereocenter as R or S when the lowest priority group is away from you or directly toward you (the two "easier" scenarios). We also talk about the "Double Switch" (a nice organic life hack) for when the lowest priority group of a stereocenter is neither facing away from you nor toward you.
