This is why methane has a very low boiling point of -161. A molecule with a net dipole moment of zero is classified as nonpolar.
CH4 Boiling Point and the Role of Dispersion Forces
Since methane is a nonpolar molecule due to its symmetric charge distribution, it does not possess a permanent dipole moment required to engage in dipole-dipole interactions with other methane molecules. Comparison with Polar Molecules To fully appreciate why methane does not engage in dipole-dipole forces, it is helpful to compare it with a molecule like water (H2O).
Consequently, water molecules are held together by robust dipole-dipole interactions, in addition to hydrogen bonding. These forces arise from the electrostatic attraction between the positive end of one polar molecule and the negative end of another.
CH4 Boiling Point and the Absence of Dipole-Dipole Forces
These forces are generally much weaker than dipole-dipole forces, which explains methane's low boiling point. The strength of dispersion forces in methane is relatively low due to its small molecular size and low polarizability.
