Is SO3 a polar or nonpolar molecule?

SO3 is generally considered a nonpolar molecule due to its symmetrical trigonal planar shape, which causes dipole moments to cancel out.

What types of intermolecular forces exist besides dipole-dipole interactions?

Other common intermolecular forces include London dispersion forces (induced dipole-induced dipole interactions) and hydrogen bonds, which are typically stronger than dipole-dipole forces.

Why are dipole-dipole interactions the strongest forces in SO3 despite its nonpolar nature?

Although SO3 is overall nonpolar, it has localized regions of electron density asymmetry that induce dipole-dipole interactions stronger than dispersion forces but weaker than hydrogen bonds.
