WebbFor clockwise direction, designation is R–, rectus, means “right” in Latin. For the counterclockwise direction, the designation is S– , sinister, which means “left” in Latin. Let’s take the following molecule as an example to practice the rule: Step 1: … WebbTo determine whether the chirality center is R or S you have to first prioritize all four groups connected to the chirality center. Then, rotate the molecule so that the fourth priority group is on a dash (pointing away from you). Finally, determine whether the sequence 1-2-3 is (R) clockwise or (S) counterclockwise. Hope this helps.
