Consider the Boiling Points of the Following Compounds and Their $\quad$

question 59

Multiple Choice

Consider the boiling points of the following compounds and their solubilities in room-temperature water.Why does the solubilities in water go down as the boiling points of these alcohols go up. $\quad$$\quad$$\quad$$\quad$$\quad$$\quad$ $\quad$ $\quad$
$\begin{array}{llcc}\text { Boiling point: } & 65^{\circ} \mathrm{C} &\quad \quad \quad 117^{\circ} \mathrm{C} &\quad \quad \quad \quad \quad \quad 138^{\circ} \mathrm{C} \\\text { Solubility: } & \text { infinite } & \quad \quad \quad 8 g / 100 \mathrm{~mL} & \quad \quad \quad \quad 2.3g/ 100 \mathrm{~mL}\end{array}$

• A)Larger molecules are less attracted to one another by induced dipole-induced dipole as well as by dipole-dipole and dipole-induced dipole attractions.
• B)As the boiling increases,it is more difficult to keep the alcohol from evaporating out of solution.
• C)As the boiling point increases,the size of the alcohol molecules decreases.
• D)Larger molecules are more attracted to one another by induced dipole-induced dipole as well as by dipole-dipole and dipole-induced dipole attractions.
