Question

review the section on Bond Polarity and Partial Ionic Character and the figure that has ionic character on the Y axis and delta EN on the X axis (this is figure 9.24 on page 393 of the 8th edition).

Critique the following conclusion from can be drawn from reviewing the graph: HF is a covalent molecule and LiI is an ionic compound. Provide as much detail and explanation as possible in 100 word or less. As stated previously, equations, formulas etc. may be substituted for words.

The bond in LICI has more ionic character than the one in HCI, which has more than 3.3 the one in Cl. Here are two approaches for quantifying ionic character. Both use arbitrary cut- offs, which is not really consistent with the actual gradation in bonding: 1. AEN range. This approach divides bonds into mostly ionic, polar covalent, mostly covalent, and nonpolar covalent based on a range of AEN values (Figure 9.24). 2. Percent ionic character. This approach is based on the behavior of a gaseous diatomic molecule in an electric field. A plot of percent ionic character vs. AEN for several molecules shows that, as expected, percent ionic character generally increases with AEN (Figure 9.25A). A value of 50% divides ionic from covalent bonds. Note that a substance like Cl(g) has 0% ionic character, but none has 100% ionic character: electron sharing occurs to some extent in every bond, even between an ion pair of an alkali halide (Figure 9.25B).
