Problem 8.73 We can define average bond enthalpies and bond lengths for ionic bonds, just like we have for covalent bonds. Which ionic bond is predicted to be stronger, Na—Cl or Ca—O?
Step-by-Step Solution:

Step 1 of 5) For molecules of approximately equal mass and size, the strength of intermolecular attractions increases with increasing polarity, a trend we see in Figure 11.8. Notice how the boiling point increases as the dipole moment increases. shows the boiling points of the binary compounds that form between hydrogen and the elements in groups 4A through 7A. The boiling points of the compounds containing group 4A elements (CH4 through SnH4, all nonpolar) increase systematically moving down the group. This is the expected trend because polarizability and, hence, dispersion forces generally increase as molecular weight increases. The heavier members of groups 5A, 6A, and 7A follow the same trend, but NH3, H2O, and HF have boiling points that are much higher than expected. In fact, these three compounds also have many other characteristics that distinguish them from other substances of similar molecular weight and polarity. For example, water has a high melting point, a high specific heat, and a high heat of vaporization. Each of these properties indicates that the intermolecular forces are abnormally strong.
