The liquid that is expected to have the weakest intermolecular interaction is the liquid that has the lowest boiling point and surface tension.
<h3>What is boiling point?</h3>
The term boiling point refers to the temperature at which the atmospheric pressure and the pressure of the liquid becomes equal. The greater the intermolecular forces of attraction between molecules the higher the boiling point of the solid. Also a high surface tension indicates a strong intermolecular forces of attraction between molecules.
