The given statement CBr4 has a weaker intermolecular forces than CCl4 is False. The dominant intermolecular forces present in CBr4 and CCl4 are the dispersion forces. These type of forces depend upon the molecular weight and the shape of the molecule. Jul 30, 2015 · London dispersion forces and Keesom forces exist between molecules of the same compound, as well as between different molecules. Debye forces only exist between different kinds of molecules. London disperson forces are mistakenly considered the weakest of the van der Waals forces, yet they can often be quite strong. Account for the difference in normal boiling points based on the types of intermolecular forces in the substances. You must discuss both of the substances in your answer.

The intermolecular forces are London dispersion forces- HI has more electrons, so more instantaneous induced dipole-dipole interaction- more intermolecular force- and therefore a higher boiling point. A polar molecule with two or more polar bonds must have a geometry which is asymmetric in at least one direction, so that the bond dipoles do not cancel each other. Polar molecules interact through dipole–dipole intermolecular forces and hydrogen bonds. 2) What type(s) of intermolecular forces must be overcome when methylamine, CH3NH2, vaporizes?What types of intermolecular forces exist between HI and H2S? asked Sep 11, 2016 in Chemistry by PickardPop.

$\begingroup$ Believe Wikipedia before some other "expert" website that says "van der Waals' forces are forces that exist between MOLECULES of the same substance." Since ethanol and water aren't the same substance, I was really surprised to learn that there can't be any hydrogen bonding between them. ;-) $\endgroup$ – MaxW Mar 31 '16 at 16:10 Intermolecular forces are attractions that occur between molecules. Intermolecular forces are weaker than either ionic or covalent bonds. However, the varying strengths of different types of intermolecular forces are responsible for physical properties of molecular compounds such as...
