4. [NiCl4]2-is tetrahedral and paramagnetic, while [Ni(CN)12-is square planar In this problem, answer the series of questions to explain these difference. You will need to use the appropriate MO diagram as a guideline. A. What is the oxidation-state (ie, positive charge) on [NiCl4? B. What is the d-electron count for the Ni in [NicLF? C. What is the oxidation-state (ie, positive charge) on [Ni(CNA D. What is the d-electron count for the Ni in [Ni(CN)412 E. Select all that apply to the chloride ligand: ? a. b. c. d, e, Strong field Weak field Ïand Ï donor Ï and Ï acceptor Ï donor only F. Select all that apply to the cyanide ligand: a. b. c. d, e. Strong field Weak field Ïand Ï donor Ï and Ï acceptor Ï donor only G. Changing L from a Ï-only donor to a Ï-and Ï-donor, how do the energies of the d-orbitals change for a square planar MLs species? Select all that are true a. No change to dz2 b. No change to d c. No change to di2-ya d. ds is raised in energy e. dz2 is raised in energy f. dsy is raised in energy g d is lowered in energy h. dzz is lowered in energy i. dsy is lowered in energy Changing L from a Ï-only donor to a Ï-donor and Ï-acceptor, how do the energies of the d-orbitals change for a square planar ML4 species? Select all that are true H. a. No change to dz2 b. No change to d c. No change to dx2-y2 d. dz is raised in energy e. dx2-y2 is raised in energy f. dsy is raised in energy g, az is lowered in energy h. dz2 is lowered in energy i. dsy is lowered in energy
