Draw the molecular orbital diagram for N2. Molecular Orbitals for N2. Mo bonding in f2 and o2 chemistry libretexts construct the molecular orbital diagram for n2 and then identify the bond order. N2 molecular orbital diagram with nitrogen we see the two molecular orbitals mixing and the energy repulsion. MO Diagram for HF The AO energies suggest that the 1s orbital of hydrogen interacts mostly with a 2p orbital of fluorine. However, this species has four valence electrons, and its configuration would be 1σ 2 2σ 2. The given electron configuration for the excited state N 2 is: (σ 1s 2)(σ* 1s 2)(σ 2s 2)(σ* 2s 2)(π 2p 4)(σ 2p 1)(π* 2p 1) From this, we can fill-up the molecular orbital diagram … Then just fill the. N 2 the animation below shows the bonding interaction of nitrogen 2 p z orbitals on two nitrogen atoms as they approach. The F 2s is nonbonding. How to compare the energies of sigma and pi bonds in molecular orbitals of diatomic heteronuclear species? 2.
