2. Construct an MO diagram for the square planar XeH4 molecule which has D4h symmetry a. Sketch the group or SAO orbitals for the terminal hydrogens and assign symmetry labels. b. For each of the group orbitals, determine which valence s and p orbitals of the central carbon are of suitable symmetry for interaction and bonding. Assign symmetry labels. c. Draw a qualitatively correct energy-level diagram for the XeH4 molecule. Place all valence electrons in appropriate MOs and label MOs with appropriate symmetry label. d. Which of the MO's correspond to o and a bonding MOs? Which correspond to the lone pair electrons? Further, mark each as bonding, nonbonding, or antibonding. e. Calculate the average XeH bond order in XeH4 by calculating the net number of bonds and dividing by the number of XeH groups
