(d) Draw an MO diagram for Bi

using only the Bi 6p AOs. Place the Bi-Bi bond

along the z-axis.

(e) Draw an MO diagram for N

using only the N 2s and 2p AOs. Place the N≡N

bond along the z-axis. The N 2s and 2p orbitals are the nitrogen valence orbitals.

SIMPLIFICATION: DO NOT COMBINE 2s ORBITALS WITH 2p ORBITALS.

(f) Draw an MO diagram for CO using only the C and O 2s and 2p AOs. Place the

C≡O bond along the z-axis. The C and O 2s and 2p orbitals are the nitrogen

valence orbitals. SIMPLIFICATION: DO NOT COMBINE 2s ORBITALS WITH

2p ORBITALS.

(g) Calculate the bond orders for each of the above molecules.

(h) Please draw the Lewis structures for each of the above molecules.
