Web(Crystal Field Theory) Which one of the following statements is FALSE? (a) In an octahedral crystal field, the d electrons on a metal ion occupy the egset of orbitals before they occupy the t2gset of orbitals. (b) Diamagnetic metal ions cannot have an odd number of electrons. (c) Low spin complexes can be paramagnetic. WebMar 24, 2024 · From the point of view of crystal field theory, it means that the crystal field splitting energy increases. This is only because the ligands are assumed to only donate electron density. That is, the t2g orbitals can apparently never get any lower in energy than the free-ion d orbital energies (which isn't true in real life). IMPORTANT NOTE: dutchess county surrogate\u0027s court
