Chapter , Problem 18E

(choose chapter or problem)

Which type of intermolecular force accounts for each of these differences?

(a)  \(\mathrm{CH}_{3} \mathrm{OH}\)  boils at \(65^{\circ} \mathrm{C} ; \mathrm{CH}_{3} \mathrm{SH}\)  boils at  \(6^{\circ} \mathrm{C}\)

(b)  \(\mathrm{Xe}\) is a liquid at atmospheric pressure and \(120 \mathrm{~K}\), whereas \(\mathrm{Ar}\) is a gas under the same conditions.

(c)  \(\mathrm{Kr}\), atomic weight 84 , boils at  \(120.9 \mathrm{~K}\), whereas \(\mathrm{Cl}_{2}\), molecular weight about 71 , boils at  \(238 \mathrm{~K}\).

(d) Acetone boils at  \(56^{\circ} \mathrm{C}\), whereas 2 -methylpropane boils at

\(-12^{\circ} \mathrm{C}\).
