Molecular Orbital Diagrams (H2 and He2) One of the strengths of molecular orbital theory is its ability to describe the energy of both occupied and unoccupied molecular orbitals for a molecule. F 2 has a bond order of 1 Adding an electron will add to an anti-bonding orbital and decrease the bond order to 0.5 Removing and electron will remove from an anti-bonding orbital and increase the bond order to 1.5 Therefore F 2+ will have the highest bond order and strongest bond F 2-will have the weakest bond and F2. The net contribution of the electrons to the bond strength of a molecule is identified by determining the bond order that results from the filling of the molecular orbitals by electrons. This pairs up with the electron in the highest occupied σ-orbital. Home. But the answer is N2.

In F2 the bonding is pure covalent, with the bonding electrons shared equally between the two fluorine atoms. What professor is this problem relevant for? Each F atom also has three pair of electrons that are not shared with the other atom. This is because oxygen's extra proton exerts just enough more force on its 2s orbitals than its 2p orbitals, and so the sigma MO's energy is lowered more than the pi MOs because the sigma MO has a bit of s-orbital identity. If you calculate their bond order, you get: "BO"_(H_2^(+)) = 1/2("Bonding" - "Antibonding") = 1/2(1-0) = 1/2 "BO"_(H_2^(-)) = 1/2("Bonding" - "Antibonding") = 1/2(2-1) = 1/2 So, neither is more stable than the other.
