Chirality priority rules
WebMar 26, 2016 · Step 1: Prioritizing the substituents. The first step is to prioritize all the substituents from one to four. Bromine is the atom with the largest atomic number, so this substituent is given the highest priority; hydrogen has the smallest atomic number, so it's given the lowest priority. Chlorine gets the number-two priority because it has a ... WebPriority Rules for Naming Chiral Centers - The R,S System 1.
