Chapter 3, Problem 37P

The percent ionic character of a bond can be approximated by the formula $\text{16}\Delta +\text{3}.\text{5}{\Delta }^{\text{2}}$ , where $\Delta$ is the magnitude of the difference in the electronegativities of the atoms (see Fig. 3.18). Calculate the percent ionic character of HF, HCl, HBr, HI, and CsF, and compare the results with those in Table 3.7.
