WebThe carbons being equivalent or nonequivalent is determined based on the same principles we discussed for proton NMR. No need for diving deeper in figuring out homotopic, enantiotopic, diastereotopic or heterotopic. WebThe first thing you need to do is determine the number of the groups that are on each atom. By groups, we mean either atoms or lone pairs of electrons. This is also known as the Steric Number (SN). Below are a few examples of steric numbers 2-4 which is largely what you need to know in organic chemistry:
