Consider this ligand substitution mechanism where the three main paths are equally likely to occur and at every path branching point, the subsequent routes are equally likely to occur.

B D Δ If each of these products were equally likely to form: The percent of trans product isomer that forms will be at least 50%. ○ In the bottom path, the Y ligand cannot enter on left side of the trigonal plane because an ethylenediamine ligand bridge (that connects the two -NH2 groups) blocks that side. The percent of A product isomer that forms will be less than 20%. ○ The three complexes shown at the beginning of the reactions paths - the molecules with the "1/3" numbers underneath them - are the same complex shown from different geometric perspectives. This is possible because the complex has an octahedral geometry.
