Web• Molecules with higher molecular weights have more electrons. This makes their electron clouds more deformable from nearby charges, a characteristic called polarizability. • As a … 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 $\ce{C_{10}}$.
