Q. Draw Lewis structures and MO diagrams for CN+, CN, and CN-. According to the Lewis model, which species is most stable? Q. Use molecular orbital theory to complete this table. Q. What is the ground-state electron configuration of O2^-? 1. (δ2s)^2(δ2s*)^2(π2p)^3(π2p*)^1 2. The corresponding diagram for cyanide, $\ce{CN-}$ is essentially identical, there will only be different orbital energies and very slightly different extends of the lobes. When forming a coordinate bond to a metal centre, cyanide will primarily attack with its highest occupied molecular orbital, the HOMO, since it is a nucleophile (attacking a ...

$\begingroup$ No, $\ce{CN-}$ is the case in point. From an MO picture, there is no non-bonding "lone pair." There's nothing to donate. Coordination between a metal and $\ce{CN-}$ in MO-world and Lewis structure world look very different. The end-result of MO and Valence Bond may be similar, but the interpretations are different. $\endgroup$ The MO diagram will be the same as the MO diagram of `O_2`, except with `1` less electron. You can either draw the `O_2` diagram and remove `1` electron, or just draw the `O_2^+` diagram. The diagram will end up as such: Notice the effect that this has on the overall bonds. Compare the MO diagram of Pt(CN)4 2- and Pt(pyridine)4 2+. Assume the pyridine molecules are all flat in the xy plane. Pyridine is a pi acceptor, but it doesn't have as many pi orbitals as CN- does.

The only difference between the MO diagrams are the relative energies of the orbitals. This video is about MO Diagram #3 - CN- Molecule/lon: CN MO; Question: Valence Bond Theory (VBTand Molecular Orbital (MO) Theory Laboratory" PART 1. A COMPARISON OF VBT AND MOTHEORY Procedure The following exercises have you completing a Lewis structure for VBT and an MO diagram for Motheory.

Molecular orbital diagrams are diagrams of molecular orbital (MO) energy levels, shown as short horizontal lines in the center, flanked by constituent atomic orbital (AO) energy levels for comparison, with the energy levels increasing from the bottom to the top. Lines, often dashed diagonal lines, connect MO levels with their constituent AO levels. This means that very occasionally an occupied MO can move up in energy as long as the occupied MOs move down more in energy. If only two MOs mix then one always goes up and one down, and the one that goes up better be unoccupied. However, once a third MO starts mixing strongly the situation is extremely complex, and this is what has happened here. MO Theory • MO diagrams can be built from group orbitals and central atom orbitals by considering orbital symmetries and energies. • The symmetry of group orbitals is determined by reducing a reducible representation of the orbitals in question. This approach is used only when the group orbitals are not obvious by inspection. The molecular orbital energy level diagram provided shows the energies of the orbitals for the valence electrons in the free radical CN. Indicate on this diagram the ground state electronic configuration of CN using the arrow notation for electron spins. * C has 4 valence electrons and N has 5 valence electrons, giving a total of 9
