Exercise 8.1 Compare and contrast the chemical and physical properties of KCl and CCl4, and compare and contrast how the chemical bonding model can be used to account for these properties. KCl is a solid up to very high temperatures. In molten form, it is an electrical conductor, and solutions of KCl in water are also electrical conductors. By contrast, CCl 4 is a liquid with a low boiling point, is not a conductor, and will not form a solution with water. The properties of KCl are consistent with an ionic model in which the atoms are bonded together by the strong electrostatic interaction of the K + ion with the Cl - ion. The properties of CCl 4 are consistent with a covalent (non-ionic) model, revealing a lack of charged species and a lack of strong electrical interactions between molecules. Exercise 8.4 Explain why an atom with a high ionization energy is expected to have a high electronegativity. Explain why an atom with a high electron affinity is expected to have a high electronegativity.
