Assume the energy level diagram shown in Figure 9.16 can be applied to the heteronuclear molecule ClO.
(a) Write the electron configuration for chlorine monoxide, ClO.
(b) What is the highest-energy, occupied molecular orbital (the HOMO)?
(c) Is the molecule diamagnetic or paramagnetic?
(d) What is the net number of σ and π bonds? What is the ClO bond order?

Data given in Figure 9.16

For O₂ and F2, the 2p MO is lower in energy than the #2p MOS. 3 o 20 TT 20 0520 JT 20 0 25 0525 N₂ molecular orbitals (b) Computer-generated molecular orbitals for N₂. Color scheme: occupied MOs are blue/green. Unoccupied MOs are red/ yellow. The different colors in a given orbital reflect the different phases [positive or negative signs] of the wave functions.
