WebOct 21, 2024 · Now, cis ligands share the d and s portions of those hybrid orbitals, but trans ligands share d, s, and one p portion of those hybrid orbitals. So trans ligands are automatically competing more for sigma bonding electron density than cis ligands. Good trans influencers "outcompete" bad ones, which is the origin of the trans influence series.
