Option A Ethane has lowest boiling point
Intermolecular Forces In terms of intermolecular forces, which member in each pair of liquids has the...
1. solids, liquids, and solutions, and intermolecular forces. 1. For each pair of substances, identify which has the highest melting point. For each, briefly explain your reasoning Ne: e. Surface area also matters. More surface area, more contact, stronger cohesion. Your book mentions this. Based on that, which do you think is most likely to be a solid at room temperature?
