Pairing energy chemistry
Webpairing energy (P) depend on the identity of both metal and ligands and it is not possible to specify a point in the spectrochemical series at which a complex changes from high spin to low spin. e.g. d4 elements : 1.) High spin: three 3d electrons occupy separate t2g and one electron occupies one of the eg orbitals -> pairing penalty avoided WebBecause it requires less energy for the electrons to occupy the e g orbitals than to pair together, there will be an electron in each of the five 3d orbitals before pairing occurs. For …
