Consider two 2p orbitals, one on each of two different atoms, oriented side-to-side, as in the figure. Imagine bringing these nuclei together so that overlap occurs as shown in the figure. This overlap results in a system of molecular orbitals.

Consider two 2p orbitals, one on each of two different atoms, that are oriented side-to-side as in the figure. Imagine bringing these nuclei together so that overlap occurs as shown in the figure. This overlap results in a system of molecular orbitals, 88-8. Construct an orbital interaction diagram for molecular orbital formation using the images that represent various orbital types (e.g., atomic, bonding, antibonding). Additionally, identify the number of nodes in each atomic and molecular orbital. Answer Bank

Draw a labelled diagram showing the atomic orbitals for N and O on each side and the molecular orbitals for NO, in the middle. The diagram should clearly show: which atomic orbitals combine to form each molecular orbital, the relative position (increasing energy going up the page) of the molecular orbitals and the locations of electrons in the atomic orbitals and in the molecular orbitals. Use your diagram to determine the following: What is the bond order? Explain how you...
