Explanation / Answer

Dispersion forces exist only in non-polar atoms or molecules

False

Dispersion force exist in all molecules

In non-polar molecules, dispersion force is the only force. In other kind of molecules , there are other forces present beside dispersion force

H-bonds can form between any molecule that includes a hydrogen

False. H-bond can be formed by those molecules in which hydrogen is attached to Nitron, oxygen or fluorine

H-bonding is a specific type of weak dipole-dipole intermolecular force

False. It is a specific type of strong dipole-dipole intermolecular force

Intermolecular forces are those that exist within a molecule

False. Intermolecular force exist between two molecules. Intramolecular force exist between molecules

Polarizability increases with molar mass

True
