Match the orbitals below to the higher and lower energy levels when an octahedral complex undergoes ligand field splitting. dx2-y2 Orbital 1 Orbital 1 Orbital 2 Orbital 3 Orbital 4 Orbital 5 L d₂2 Orbital 2 L dyz Orbital 3 dxz Orbital 4 [Choose] ◊ [Choose] ↑ [Choose] ◊ [Choose] [Choose] ↑ L dxy Orbital 5

Which statements are true regarding ligands? Select all that apply. Ligands donate all electrons involved in bonds they form with metal cations. Ligands are electron pair acceptors in coordination complexes. Ligands act as Lewis bases in coordination complexes. Ligands form ionic bonds with transition metals. All ligands with two lone pairs are bidentate. A ligand that can donate more than one electron pair to a metal cation is called a chelate. One ligand can donate only one lone pair to a metal cation.

Please answer my question!!

2. Short questions, all-or-nothing. There may be more than one answer per question. axial 3- CN NC Ni CN CN equatorial NC а. For the square base pyramidal complex [Ni(CN)s]3 shown above, of Cav point group, consider the rotation axes: 2C4 and C2. If the axial CN ligand was substituted by CO, forming [Ni(CO)(CN)4]?, maintaining the square pyramidal geometry, which symmetry elements would be retained: i. Both C4 and C2. ii. Only the C2. iii. Only the C4. iv. None of the above b. Looking at the symmetry planes: 20v, 20d; what symmetry elements would be retained if the Co substitution would occur on an equatorial CN ligand (forming again [Ni(CO)(CN)4]?) instead? The dihedral planes in this case is the mirror plane that bisects the square planar bonds. i. All ov ii. All od iii. At least 1 od iv. At least 1 oy
