This is an interactive lesson sequence to aid the learning of intermolecular forces. Hydrogen bonding the most powerful intermolecular force influencing neutral (uncharged) molecules is the hydrogen bond if we compare the boiling points of methane. In physics, chemistry, and biology, intermolecular forces are forces that act between stable molecules or between functional groups of macromolecules these forces are generally much weaker. Different types of intermolecular forces (forces between molecules.
Why do some solids dissolve in water but others do not why are some substances gases at room temperature, but others are liquid or solid what gives metals the. Molecules in liquids are held to other molecules by intermolecular interactions, which are weaker than the intramolecular interactions that hold molecules and.
