Explain how symmetry arguments are used to construct Molecular Orbitals. (As simple as possible!)
1. Use symmetry considerations to construct a qualitative molecular orbital energy level diagram for PFs - consider only s and p orbitals. 2, Give the point groups designations and show the symmetry elements used to establish that designation in the following.
[Co(NH3)6]3+ion4. Construct the MO diagram. Label all atomic, group and molecular orbitals with symmetry labels. Fill in the diagram with the appropriate number of electrons. Assume that this complex is a strong field, low spin complex.5. a) What set of orbitals is the HOMO (highest occupied molecular orbitals).b) Is this set of orbitals classified as bonding, antibonding or non-bonding (no symmetry match)?6. What set of orbitals is the LUMO (lowest unoccupied molecular orbitals)?
Sketch the molecular orbitals diagrams of BF3. Describe point by point how you obtained the diagram (symmetry, linear combination of atomic orbitals, etc.)
Using a symmetry-based approach, construct a complete molecular orbital diagram for OH2. (a) Indicate the HOMO and LUMO. (b) Draw a representation of the HOMO and LUMO. (c) If one were to react this cation with another proton to give the dicationic species [H3O] + explain what would happen to the energies of the orbitals in the OH2 diagram after this reaction. Be specific about the key features regarding the M.O. diagram in the new cation. You do NOT need...
Construct the molecular orbital diagram of He2 using appropriate molecular orbital labels and arrows to represent electrons. a) Sketch each molecular orbital. Explain HOW you identify an antibonding orbital. b) Identify the linear combination of atomic orbitals for each molecular orbital. Explain WHY there are two molecular orbitals. Explain why the He2 molecule is NOT observed experimentally. c)
What is the basis set that you will use to construct the molecular orbitals of C2H4 (ethene)?
Construct a molecular orbital diagram for the formation of N2; show only the valence orbitals of the nitrogen atom. The bond length of N-N was determined for N2 and [N2]+. if the following values were obtained: 112 and 110. What species correspond to each value. Explain
Below are four frontier molecular orbitals for N_2F_2. Designate the C_2h symmetry representation of each. Like colors represent the same sign on the wavefunction. Draw an arrow between occupied (HOMO) and unoccupied(LUMO) pair(s) that are connected by a dipole-allowed absorption.(*Note the coordinate system of each wavefunction.)
Discuss the experimental evidence supporting the existence of molecular orbitals. Explain how a chemist might measure the energy of an electron in a particular molecular orbital
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...
