WebThe Cahn-Ingold-Prelog system is a set of rules for assigning R and S (absolute configurations) to chiral centers. The idea is to assign each of the 4 atoms attached to a chiral center a priority, 1 through 4, based primarily on atomic number. Once the priorities are assigned the spacial arrangement of these 4 atoms will be in one of two ... WebWhen determining R or S, the lowest priority substituent needs to be facing towards the back, which can be done "turning" the molecule at the chirality center that the hydrogen is attached too. Some people can't visualize, or understand, how this happens so the trick is that whenever the lowest priority (this time hydrogen) is not facing the ... WebTo determine whether the chirality center is R or S you have to first prioritize all four groups connected to the chirality center.
