nonpolar molecules

Postby dtolentino1E » Fri Nov 15, 2019 11:04 am

do nonpolar covalent bond only have london dispersion forces? or can they have any of the other molecular forces?

Nonpolar covalent bonded molecules only exhibit induced dipole forces as long as they encounter a dipole or an induced dipole. So the only forces they experience are Van Der Waal's or London Dispersion forces.

To add on, non polar molecules have all their electrical charges evenly distributed, therefore there are no dipole-dipole forces. However, since all molecules experience London-dispersion forces, London-dispersion is the only intermolecular forces for non polar molecules.

Some examples of nonpolar molecules are the diatomic gases such as H2. Also for molecules if dipole moments are canceled out by each other the molecule is nonpolar. An example of a nonpolar molecule because dipoles cancel each other out is carbon dioxide because the bonds are on exact opposite sides of the central atom.

While London dispersion forces are the go-to for nonpolar molecules, make sure to also check for dipole-induced dipole intermolecular forces which is the interaction of a polar molecule and a nonpolar molecule.

All non-polar molecules have London Dispersion forces but be careful sometimes in the presence of a polar molecule they can also have dipole-induced dipole forces.
