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.
Best Answer: Dipole moment is a vector quantity. So, in symmetrical molecules, with polar bonds, dipole moment is zero because the dipole moments due to individual bonds when added vectorially, cancel each other. EXAMPLE -In BF3, u know B (Boron) has three sigma bonds, so it is sp2 hybridised. This means, that it is triangular planar by VSEPR theory.
