Intermolecular size vs Intramolecular size

[Claire_Kim_2F]

For stronger intermolecular forces are you looking for the larger molecule because it has more electrons=stronger bonds while for intramolecular forces you would look for the smaller molecule so it can be pulled in closer?

I believe that if we're talking about intermolecular forces you'd be analyzing the IMF's not the bonds so that's why you look at the size of an element. If the element is larger than it will have stronger dispersion forces.

Intermolecular forces have nothing to do with bonding but rather the attractions BETWEEN the molecules. Because of this, larger atoms in molecules have stronger intermolecular forces because they have more electrons which in turn can attract positively induced atoms while not explicitly BONDING with them. I hope this helps!
