Use the molecular orbital energy level diagram to show that N2 would be expected to have a triple bond, F2, a single bond and Ne2, no bond.
The general sequence of the energy level of molecular orbitals for nitrogen is:
The molecular orbitals in the sequence of their energy levels for the given molecules are given below:
Since the bond order is 3, N2 has a triple bond.
F2 = σ 1s2, σ * 1s2, σ 2s2, σ* 2s2, σ 2px2, π 2px2 = π2py2
The molecular orbital of Fluorine is given
The bond order of F2 =
Thus, when bond order is 1, the number of bonds is also 1.
Ne2 = σ 1s2, σ * 1s2, σ 2s2, σ* 2s2, σ 2px2, π 2px2 = π2py2, π*2px2 = π*2py2
The bond order of Ne2==0
Thus, Ne2 has no bond.
