WebOct 19, 2016 · Crystal Field Theory: Crystal field theory has several limitations. It takes into account only the d-orbitals of the central atom; the s and p orbitals are not considered. In addition, this theory fails to explain the reasons for large splitting and the small splitting of some ligands. 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.
