Ethanol and dimethyl ether has same molecular formula, C 2 H 6 O. The reason behind the fact that dimethyl ether has a boiling point that is lower than the boiling point of ethanol is to be explained. Concept Introduction: The various kinds of interactions that bind a molecule together are known as intermolecular forces. These forces can be dispersion, dipole-dipole, ion-dipole, and hydrogen bonding. The boiling point of a substance depends upon the intermolecular forces present in a molecule. When hydrogen is covalently bonded to a very small, highly electronegative atom (usually fluorine, oxygen, or nitrogen), the result is a molecule with a large dipole moment. This leads to a particularly strong type of dipole–dipole attraction traditionally called hydrogen bonding
