Suppose that you have 16 diatomic molecules or ions with the valence molecular orbital arrangement shown here (Figure 1), but with different numbers of valence electrons. Species 1 has one valence electron, Species 2 has two valence electrons, etc. Classify each as diamagnetic or paramagnetic.

One of the molecular orbitals of the H2- ion is sketched below:

(a) Is the molecular orbital a s or p MO? Is it bonding or antibonding?

At high temperatures, sulfur vapor is predominantly in the form of S₂(g) molecules. (a) Assuming that the molecular orbitals for third-row diatomic molecules are analogous to those for second-row molecules, construct an MO diagram for the valence orbitals of S₂(g).

Suppose that you have 16 diatomic molecules or ions with the valence molecular orbital arrangement shown here (figure 1), but with different numbers of valence electrons. species 1 has one valence electron, species 2 has two valence electrons, etc. classify each as diamagnetic or paramagnetic.

Assume that the MOs of diatomics from the third row of the periodic table, such as P2, are analogous to those from the second row.

c. For the P2 molecule, how many electrons occupy the MO in the figure?

Assume that the MOs of diatomics from the third row of the periodic table, such as P2, are analogous to those from the second row.

a. Which valence atomic orbitals of P are used to construct the MOs of P2?

One of the molecular orbitals of the H2− ion can be sketched as follows:

a. Is the molecular orbital a 𝜎 or 𝜋 MO? Is it bonding or antibonding?

(b) How many of the MOs from part (a) would be occupied by electrons?
