Evaluating Lewis Structures

Question 1
For the following molecules with the given σ-framework hybridisation, draw an MO Diagram for the π-bonding between Xe and O, assuming that d orbitals are low enough in energy to form bonds and draw a Lewis Structure from the MO Diagram:

1. XeO₃ (C_3v, hybridisation: sp³) [Solution]
2. XeF₂O₃ (D_3h, hybridisation: sp³d) [Solution]
