The MO diagram, the number of unpaired electrons, the number bonds in BN molecule has to be predicted using MO theory. Concept Introduction: Molecular orbital theory: The atomic orbitals of the atoms constituted in a molecule are combined to produce new orbitals are called Molecular Orbitals. Like atomic orbitals, a molecular orbital can accommodate maximum two electrons and the two electrons must have opposite spins (Pauli Exclusion Principle). The numbers of MO’s are equals to the number of atomic orbitals are combined in such a way that the linear combination of similar atomic orbitals to form one bonding and one anti-bonding MO’s. The bonding MO’s are lower in energy than the anti-bonding MO’s. HOMO is the highest energized occupied orbital in the MO’s. Relative energy levels of molecules are according to the energy levels of atomic orbitals. LUMO is the lowest energized orbital in the MO’s. Bond order can be calculated using below formula bond order = bonding molecularorbital -antibonding molecular orbitals 2
