• The traditional chemical approaches, Lewis electron dot structures and molecular orbital theory, predict the relative bond orders of boron monofluoride, carbon monoxide, and dinitrogen to be BF < CO < N2. This is quantified by quantum mechanical, theoretical studies that show the bond orders to be ∼1.4, ∼2.6, and ∼3.0, respectively. These results also confirm the chemical intuition that the change in bond order is primarily due to the π component. The differences in bond order have a dramatic effect on the ligand behavior of the three molecules, particularly the propensity of BF to function as a bridging ligand.
