are nonpolar, so the only intermolecular attractive forces are London dispersion forces. I. 2. is solid because the electrons in the I. 2. molecule occupy a larger volume and are more polarizable compared to the electrons in the F. 2. molecule. As a result, the dispersion forces are considerably stronger in I. 2. compared to F. 2. These are intra-molecular forces. Intermolecular Forces Intermolecular Forces: is an attractive force between neighbouring molecules. Intermolecular forces are weak compared to covalent bonds. Intermolecular forces act between different molecules. They are caused by weak attractive forces between very small dipoles in different molecules. Comparison between Solids, Liquids and Gaseous.

The interparticle force is the same as the intermolecular force: the ionic bond and it is the strongest of the interparticle forces. With the exception of ionic compounds, the words polar and nonpolar only pertain to MOLECULAR substances and the difference between them dictates the strength and type of IMF.
