The molecular orbital diagram of NO shown in Figure 10.47 also applies to OF. Draw the complete molecular orbital diagram for OF. What is the OF bond order? Figure 10.47 Molecular orbital diagram for nitric oxide (NO). The molecular orbital diagram for NO predicts a bond order of 2.5 and predicts that the molecule is paramagnetic with one unpaired electron. These predictions are verified by experimental measurements.

Based on hybridization, a Csp2–Csp2 bond should be shorter than aCsp3–Csp3 bond because it is formed from orbitals having a higherpercent s-character. Explain is this statement true or not?
how is molecular orbital theory an improvement of valence bond theory? valence bond theory is too complicated because the orbital overlap is hard to draw. MO is easier MO theory allows us to directly solve schrodingers equation for a molecule valence bond theory is oversimplification because it uses atomic orbitals in a molecular context. mo corrects for this or MO theory is not an improvement becayse it requires too much math
