Apr 10, 2020 · There are three intermolecular forces of ethanol. They are London dispersion, dipole-dipole and the hydrogen bond. All three of these forces are different due to of the types of bonds they form and their various bond strengths. The first force, London dispersion, is also the weakest. London dispersion forces, which result from short-lived dipoles induced by fluctuations in the electron shell of molecules, are also present. They are responsible for the weak interactions between the alkyl chains, like in other alkanes and non-polar molecules.
