Webfrom the observer and the other three groups have a priority sequence X→Y→Z in a clockwise direction, the chiral center will have a R configuration; otherwise it is defined as an S configuration. The R/S system can be used for other chiral molecules without a chiral center (e.g., planar chirality) as well [6]. 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 ...
