WebAug 27, 2024 · How does melting point affect bonding? Boiling points and melting points The overarching principle involved is simple: the stronger the noncovalent interactions between molecules, the more energy that is required, in the form of heat, to break them apart. Higher melting and boiling points signify stronger noncovalent intermolecular forces. 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.
