In contrast, each oxygen atom is bonded to two H atoms at the shorter distance and two at the longer distance, corresponding to two OH covalent bonds and two OH hydrogen bonds from adjacent water molecules, respectively. Consequently, we expect intermolecular interactions for n-butane to be stronger due to its larger surface area, resulting in a higher boiling point. Calculate the amount of heat that must be absorbed by 10.0 g of ice at 20C to convert it to liquid water at 60.0C. For example, Xe boils at 108.1C, whereas He boils at 269C. Because each end of a dipole possesses only a fraction of the charge of an electron, dipoledipole interactions are substantially weaker than the interactions between two ions, each of which has a charge of at least 1, or between a dipole and an ion, in which one of the species has at least a full positive or negative charge.

Methane and its heavier congeners in group 14 form a series whose boiling points increase smoothly with increasing molar mass. Because the electrons are in constant motion, however, their distribution in one atom is likely to be asymmetrical at any given instant, resulting in an instantaneous dipole moment. 0 4 F J Z \ ^ xfW jl5(M London dispersion forces are due to the formation of instantaneous dipole moments in polar or nonpolar molecules as a result of short-lived fluctuations of electron charge distribution, which in turn cause the temporary formation of an induced dipole in adjacent molecules; their energy falls off as 1/r6. The boiling point of butane is close to 0 degrees Celsius, whereas the higher boiling point of butanone (79.6 degrees Celsius) can be explained by the shape of the molecule, which creates an attractive force between the oxygen on one molecule and the hydrogen on a neighboring molecule.
