23. A homonuclear diatomic system has the ground-state molecular orbital (MO) configuration 1g21u22g22u23g21u41g2. Answer the following: (a) What is the number of bonding electrons? (b) Find the bond order. (c) What would you expect the effect to be on the dissociation energy of this molecule when an electron is removed (a) from the 1gMO ? (b) from the 3gMO ? Q4. Indicate whether you expect each of the following homonuclear diatomic MOs to be bonding or antibonding. Sketch the MO in each case: (a) u (b) u, (c) g Q5. Arrange bond energies of O2,N2,O2+, and N2+in increasing order
