Sketch the qualitative molecular orbital energy diagram for water. Inclu symmetry labels for each molecular orbital. Indicate whether each molecular bonding, nonbonding, or anti-bonding and don't forget the σ and π labels. Remember to construct appropriate group orbitals from the outer H-atoms. Describe the bonding of this molecule from the MO diagram you constructed, including the location s) of the lone pair(s). The 2s and 2p energies for oxygen are -26 and -13 eV, respectively, and the ls energy of...
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.
Beryllium hydride, BeH_2, is linear in the gas phase. Construct a molecular orbital energy level diagram for BeH_2. Include sketches of the group orbitals, and indicate how they interact with the appropriate orbitals of Be.
Construct a molecular orbital diagram showing the relative energy spacing of cyclopentadienyl. Use real energy values. Calculate the coefficients in front of the five pi orbitals, giving us the five orthogonal Huckel pi molecular orbitals of cyclopentadienyl. Draw all possible pi molecular orbital orientations for cyclopentadienyl, including the nodal planes, relating them to the energy levels determined in the first question.

2. Use the group orbitals of CH3 and CH2 to create a Qualitative Molecular Orbital Theory diagram of the bonding in CH3NH2 (14 electrons) Draw a separate picture attempting to illustrate what the molecular orbital will look like A few points to help you in making this diagram: • Better overlap (as in head-on versus side-by-side) leads to greater stabilization of bonding orbital • If bonding interaction is highly stabilized, the anti-bonding interaction is even more destabilized • The 2p...
