Explanation / Answer

A. (a) n-Butane has a higher boiling point than propane because of stronger dispersion forces. As the molecules become larger, the dispersion forces (van der Waals interection) increases, resulting in higher boiling points.

(b) 1- butanol has a higher boiling point than diethyl ether, because of hydrogen bonding influences. Hydrogen bonding is not possible in case of diethyl ether, while 1-butanol has very strong hydrogen bonding interactions. Thus, boiling point of 1-butanol is higher than diethyl ether.

B. (a) Cl2CO has a higher boiling point than H2CO its greater molar mass and stronger dispersion forces. Even though dipole-dipole interactions are stronger in Cl2CO than H2CO, which also contribute to it higher boiling point, that applies to only certain orientations of the interacting molecules.

(b) SO3 has a higher boiling point than SO2, because of its greater molar mass and stronger dispersion forces. SO3 is a bigger molecule than SO2 which results in much stronger van der Waals interactions, resulting in higher boiling points.
