Crystal Field Question. I understand that octahedral shapes have larger splitting energies then in tetrahedral complexes. And it would take more energy to split more electrons. So would the order be from Highest to Lowest: B>A>C where A, B, C are the compounds listed in their respective orders. Between Ni(H20)s2+ ; Ni(en)32+; and lowest and why? Cu(CN)42- which has highest splitting and which has
What is spin pairing energy (SPE)? How is it related to crystal field splitting energy? Relate the splitting energy for octahedral and tetrahedral complexes and briefly explain why tetrahedral complexes are almost always high spin

What is spin pairing energy (SPE)? How is it related to crystal field splitting energy? Relate the splitting energy for octahedral and tetrahedral complexes and briefly explain why tetrahedral complexes are almost always high spin.
i) Consider the crystal field diagram for a tetrahedral complex and the relative d orbital configuration. Show the purple colour of MnO4 - cannot be from d-d transitions and briefly explain your answer. ii) Draw a simplified molecular orbital diagram (i.e. like those used for ligand field theory in lectures) to show the possible origin of the transition responsible for the purple colour of an aqueous KMnO4 solution. iii) MnO4 - ions actually have two intense transitions, one at 541...
