However, the varying strengths of different types of intermolecular forces are responsible … WebFeb 2, 2024 · And an atom that has higher polarizability has stronger dispersion forces. As a result, it will have higher melting point in comparison. Noble gases illustrate this. These compounds are inert and only interact with each other through weak intermolecular forces. Thus, radon has the highest melting point and neon has the lowest melting point.

WebJan 29, 2014 · A solid with high intermolecular forces will require more energy (i.e., a higher temperature) to overcome these attractions and will have a higher melting point. Conversely, as the temperature of a liquid sample decreases, the average kinetic energy of the molecules decreases and they move more slowly. WebWhen he's looking at the -OH bonds for each molecule, he's imagining other molecules of the same chemical in close proximity engaging in hydrogen bonding thus creating stronger attractions between the molecules which affects their boiling points. This is also why he investigates their London dispersion forces which is weaker intermolecular force. portsmouth public defenders office
