Construct an approximate molecular orbital energy diagram for homonuclear diatomic F2. Considering only the valence atomic orbitals on fluorine. Show the sigma and pi interaction between orbitals of the same symmetry and then rank these on your diagram in terms of increasing energy (be sure to draw pictures of the orbital interactions or the final MOs). Write out the electron configuration and determine the bond order of F2.
For which homonuclear diatomic molecules is the O2p bonding orbital lower in energy than the A2p bonding orbitals? • Enter the molecular formulas for the two species that apply. Provide your answer below: and o
1. For the homonuclear diatomic molecules across the periodic table from H2 to Nez (10 molecules in all), make a MO diagram like the figure, and fill in the electrons. Be sure to get the order of the orbitals correct (see Fig. 11.14 of textbook). For each molecule, give the bond order and whether or not it's paramagnetic (unpaired spins). I know this seems like a pretty basic question, but it's important for chemists to have this model embedded in...
Molecular orbitals. Consider the following diatomic molecules: H2*, H2, Li2, N2, O2. For each molecule, (A) determine the number of electrons N; (B) give the index i of the HOMO (1 is lowest energy orbital, 2 is next one up, etc); (C) sketch the shape of the HOMO, indicating the signs of the lobes; (D) indicate the symmetry of the HOMO (o, T, 6) Molecular orbitals. Consider the following diatomic molecules: H2*, H2, Li2, N2, O2. For each molecule, (A)...

Using the molecular orbital energy ordering for second-row homonuclear diatomic molecules in which the π2p orbitals lie at lower energy than the σ2p, predict the bond order in a molecule or ion with each of the following numbers of total valence electrons.(Use the drawing MO energy diagrams) Will the molecule or ion be diamagnetic or paramagnetic? Part A Determine the bond order in a molecule or ion with 4 valence electrons. Part B Will this molecule or ion be diamagnetic...
Differentiate between the LCAO approximation 1 and LCAO approximation 2. Illustrate how these 2 approximations pertain to the orbitals of the homonuclear molecules diborane(Br2) and difluorine(F2). Explain the origin of the different energy ordering of the molecular orbitals in these two molecules. Explain what is meant by the following two terms used in molecular orbital theory. In both cases use molecular hydrogen (H2) to illustrate your answer. (G) LCAO (ii) HOMO ii) Differentiate between the LCAO Approximation 1 and LCAO...

5. Suppose that photoelectron spectroscopy is done on a 2nd-row homonuclear diatomic molecule. Photons with energy 21.21 eV are used, and electrons are ejected with kinetic energies of 11.01 eV, 8.23 eV, and 15.22 eV. (a) Sketch the molecular orbital energy level diagram for the molecule, showing the ionization energies of the three orbitals. Assume that these are the only three filled or partially-filled orbitals and that the molecule is in the ground state. (b) What are the possible identities...
