WebJun 30, 2024 · Jun 30, 2024 The stronger the IMF, the higher the boiling point will be Explanation: Take, for example, hydrogen bonding. Hydrogen bonding occurs when a hydrogen atom combines with either nitrogen, oxygen, or fluorine ( H 2O ). Hydrogen bonding results in the strongest intermolecular forces, and therefore will always have the … WebLook at the boiling points. Interaction is based on geometry (surface area) and polarizability, among other things - and the phase: solid, liquid, vapor. Molecular weight is not diagnostic. SiH4 is "fluffy" versus methane being "hard." Compare the melting and boiling points of decane and isodecane versus adamantane, all being $\ce{C_{10}}$.
