1 Answer
Yes, substances with polar molecules have a stronger attraction between their molecules than a substance with nonpolar molecules.
Explanation:
If you have a substance with nonpolar molecules , the only Intermolecular Forces of Attraction that exist are London-Dispersion forces, which are very weak.
However, if you have a substance with polar molecules, then not only are there London-Dispersion forces, but also Dipole-Dipole forces, which are stronger than London-Dispersion forces.
Therefore, a polar substance will have a stronger attraction between its molecules than a substance with nonpolar molecules.
