WebJan 22, 2001 · Three groupings are considered in the following paragraphs. 1. I- < Br- < Cl- < F-. The crystal field model looks at electrostatic repulsions between the ligands and electrons in d-orbitals on the metal ion. The smaller the ligand, the closer it comes to the metal ion and thus the greater the repulsion. 2. WebThere are a number of different ways by which we can explain these. The simplest approach to do this – how we will handle this – is by using crystal field theory. To start off, we need to remind ourselves that there are five different d orbitals: The five different d orbitals.
