Webnity. The key to this system is the CIP priority rule, which defines the substituent priority based on the following criteria:1) Higher atomic number or higher atomic mass is given higher priority; 2) when the proximate atom of two or more of the substituents are the same, the atomic number of the next atom determines the priority; 3) double ...

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 ... WebAbsolute configuration uses a set of rules to describe the relative positions of each bond around the chiral center atom.
