1) Consider the molecule [Nicl]. It is tetrahedral geometry and Ta symmetry Consider the sigma-bonding and determine a reducible representation for the molecule. Determine the irreducible representation. Draw a qualitative molecular orbital diagram with electrons and symmetry labels. Consider carefully the oxidation state of the metal and ligands and fill in electrons thoughtfully. You will only utilize the 3d orbitals on Nickel, not the 4s or 4p. The ligand group orbitals of the chlorine ligands should be lower in energy...
