Using the molecular orbital energy ordering for second-row homonuclear diatomic molecules in which the 20 orbitals lie at a lower energy than the 02p, draw the MO energy diagrams and predict the bond order in a molecule or ion with each number of total valence electrons. Will the molecule or ion be diamagnetic or paramagnetic? a) 6 valence electrons b) 9 valence electrons c) 12 valence electrons

Assuming that the molecular orbital energy level diagram for homonuclear diatomic molecules can be applied to heteronuclear diatomic molecules, arrange the NO, NO- and NO+ in order of decreasing bond length, from longest to shortest. Explain why that order is accurate using molecular orbital diagrams and what you know about how bond lengths behave.

Outline the rules of the building-up principle for homonuclear diatomic molecules.

Which statement is not true of molecular orbitals? A)The number of molecular orbitals formed is always equal to the number of atomic orbitals combined. B)A molecular orbital can accommodate up to two electrons. C)When electrons are added to orbitals of the same energy, the most stable arrangement is predicted by Hund's rule. D)Low-energy molecular orbitals fill before high-energy molecular orbitals fill. E)Antibonding molecular orbitals are higher in energy than all of the bonding molecular orbital

Consider the molecular orbital diagram shown below, a diagram that is often applied to the first row diatomic molecules.

Consider the molecular orbital diagram shown below, a diagram that is often applied to the first row diatomic molecules. Note that this diagram comprises orbitals derived from the n = 2 valence shell of orbitals (2s and 2p). Use this diagram to determine (1) if the following diatomic molecules or ions will be diamagnetic (all electrons paired) or paramagnetic (one or more unpaired electrons), and (2) for paramagnetic species, the number of unpaired electrons.O2, N2, CO, NO, NO-, NO+, CN-,...
