Chapter 11, Problem 15E

Indicate the most important type of intermolecular attraction responsible for solvation in each of the following solutions:

(a) the solutions In Figure 11.7

(b) methanol, ${\text{CH}}_{\text{3}}\text{OH,}$ dissolved in ethanol, ${\text{C}}_{\text{2}}{\text{H}}_{\text{5}}\text{OH}$

(C) methane, CH₄, dissolved in benzene, ${\text{C}}_{\text{6}}{\text{H}}_{\text{6}}$

(d) the polar halocarbon ${\text{CF}}_{\text{2}}{\text{C1}}_{\text{2}}$ dissolved In the polar halocarbon ${\text{CF}}_{\text{2}}{\text{C1CFCI}}_{\text{2}}$

(e) ${\text{O}}_{\text{2}}\text{(1)}$ in ${\text{N}}_{\text{2(1)}}$

Figure 117 As potassium chloride (KCI) dissolves in water, the ions are hydrated. The polar water molecuIes are attracted by the charges on the K⁺ and Cl^- ions. Water molecules in front of and behind the ions are not shown.
