All compounds experience and must overcome dispersion forces. The other forces depend on the polarity of the molecule. Is this molecule polar or nonpolar?

Any molecule which exhibibits any other intermolecular force than dispersion forces is a polar molecule.

Note: This question is incomplete as no compound is given as an example.

Explanation:

The only intermolecular force that non-polar molecules exhibit is the London dispersion forces. Polar molecules can bond with each other via dipole-dipole interactions or through hydrogen bonding both of which are generally stronger than London dispersion forces. Polarity also affects the strength of intermolecular forces.

If the molecule is polar, it has areas of partial positive and partial negative charges which can interact with the areas of partial negative and partial positive charges in a second molecule. This type of force is called a dipole-dipole interaction.

A hydrogen bond is a type of attractive (dipole-dipole) interaction between an electronegative atom and a hydrogen atom bonded to another electronegative atom. This bond always involves a hydrogen atom.
