Since alkanes are almost non-polar molecules (because of the covalent nature of C-C and C-H bonds and very little difference of electronegativity between carbon and hydrogen atoms), therefore, these intermolecular forces of attraction are of van der Waals type which mainly depend upon the shape and hence the structure of the molecule.

H2O CCl4 HF CH3COOH PH3. The intermolecular forces between molecules are relatively weak in liquids that are volatile, so the particles don't need to much kinetic energy to escape from the surface of your skin.
