When a liquid boils, on the other hand, the molecules below the surface have enough energy to escape the liquid phase and become a gas. but lets' look at D anyway, just to make sure we didn't for these compounds. Except in some rather unusual cases, the hydrogen atom has to be attached directly to the very electronegative element for hydrogen bonding to occur. Even lower molecular weight examples are given in Ref.1: Easily, if you look at $\ce{C10H20}$ vs $\ce{C9H20}$ isomers, you find the boiling points of 2,2,5,5-hexamethylhexane, 2,2,4,5-hexamethylhexane, and 2,2,3,5-hexamethylhexane, all of which are $\ce{C10H22}$ isomers, are $137.5, 147.9,$ and $\pu{148.4 ^{\mathrm{o}}C}$, respectively. Legal. One can construct systems in which van der Waals forces outweigh ionic repulsion. They have the same number of electrons, and a similar length. Each of the highly electronegative atoms attains a high negative charge and has at least one "active" lone pair. Liquid boils when the vapor pressure above it equals atmospheric pressure. This phenomenon can be used to analyze boiling point of different molecules, defined as the temperature at which a phase change from liquid to gas occurs.
