i read in my textbook that the energy diagram of moleculal orbits is different for atoms nitrogen and below them. my question is which one of the energy diagrams to use in heteronuclear compounds like CO?
(In heteronuclear diatomic molecules, atomic orbitals only mix when the electronegativity values are similar.) (While MOs for homonuclear diatomic molecules contain equal contributions from each interacting atomic orbital, MOs for heteronuclear diatomics contain different atomic orbital contributions.) (Orbital interactions to produce bonding or antibonding orbitals in heteronuclear diatomics occur if there is sufficient overlap between atomic orbitals, as determined by their symmetries and similarity in orbital energies.)
