(a) Draw the molecular orbital energy-level diagram for N₂ and label the energy levels according to the type of orbitals from which they are made, whether they are σ- or π-orbitals, and whether they are bonding or antibonding.

(b) The orbital structure of the heteronuclear diatomic ion NO⁺ is similar to that of N₂. How will the fact that the electronegativity of N differs from that of O affect the molecular orbital energy-level diagram of NO⁺ compared with that of N₂? Use this information to draw the energy-level diagram for NO⁺.

(c) In the molecular orbitals, will the electrons have a higher probability of being at N or at O? Why?
