The dipole moment of a molecule can be predicted by looking at the molecule's structure and the location of the dipoles within the molecule. When a molecule has no dipole moment, it will be nonpolar. A molecule with a dipole moment will be polar.
Hydrogen bonding is an exceptional case of dipole-dipole interactions. In oxygen gas, intramolecular forces are nonpolar covalent. The forces are covalent for the same reasons as above: oxygen is a nonmetal, and in oxygen gas, oxygen is bonded with only oxygen.
