Question

Could you show how to do step by step,please?

3. Consider (Cr(CN).]*: (donor/acceptor) --CN is a _ (strong/weak)-field ligand because of interactions with the metal ion --In this complex, Cr-* is a d ion Therefore, the number of unpaired electrons in (Cr(CN).)" is Draw an orbital diagram showing the distribution of electrons: Calculate the spin-only magnetic moment of [Cr((CN).]" (in his units): Calculate (i) the Ligand-Field Stabilization Energy (as a function of Ac), (ii) the Coulombic energy (as a function of 11.) and (iii) the exchange energy (as a function of 11.) for (Cr((CN).]4.. You must show your work.
