R,S -System: rules for assigning R or S were developed by Cahn, Ingold and  Prelog. R : rectus, straight, correct. Order of groups is clockwise (CW) S : sinister, left. Order of groups is counterclockwise (CCW) Priority rules  Each atom bonded to the chiral center is assigned a priority based on  atomic number; the higher the atomic number, the higher the priority.  If priority cannot be assigned per the atoms bonded to the chiral center,
