ArH+ can be viewed as either a covalent bond between Ar+ and H or as a dative bond between Ar and H+ . Draw coupling diagrams for both cases. Based on the ionization energies ofAr (15.8 eV) and H (13.6 eV), which bonding picture is more accurate? (6 points)  \n2. In last week’s homework, you were asked to build a coupling diagram for NH. Complete the family of neutral NHn compounds by adding H atoms to NH, etc. until it is saturated (until you can’t add more H) . For each new compound, (i) generate a coupling diagram;  \n(ii) identify the multiplicity of the compound and if it is an open shell radical or a closed shell species; and (iii) identify the nominal bond angles for each compound with more than two atoms. (6 points)  \n3. An additional hydrogen in the form of H+ can be added to the largest structure from problem  \n2. Identify this compound and identify the type of bonding involved. (2 points)  \n4. Start with PO from Homework Set \\#6 and build the HnPO family until saturated. Assume there is no recoupling and that the 􀁓 bond is not disrupted. (2 points)  \n5. What happens to the bonding if O2 is ionized to O2+? Write the coupling diagram for O2+ and predict whether its bond length will be longer or shorter than that ofO2. Why? (4 points)  \nExtra Problems (ungraded)  \n1. Write coupling diagrams for the following compounds. For each case, identify the multiplicity of the compound and the type of bonding that is involved. (a) CF (b) F2. Answers: (a) doublet, polar covalent (b) singlet, non-polar covalent  \n2. Account for the bonding in OF2. What is the nominal bond angle of singlet OF2, and what forces might be responsible for distorting it from that value? Do you think the real bond angle will be larger or smaller than the nominal bond angle? Why? Do you think the bond angle is larger, smaller, or comparable to H2O?
