The Carbon has 2 pairs of electrons, each being pulled by one O; so there must be a partial positive on the carbon and a partial negative on both the oxygens, shouldn't there? The BF3 molecule has a symmetrical trigonal planar geometry, like the SO3 molecule. O c. NH,, A:Hybridization of central atom in MgCl2 is sp For example, in the molecule BF3, each BF bond has a dipole moment with a partial negative charge on the fluorine (it is much more electronegative than the boron), but the shape of the molecule (trigonal planar) is such that the bond dipole moments add up to zero. Magnetic dipoles are different than electric dipoles in that, there are no magnetic monopoles, only dipoles. Nonmetals are more electronegative than metals.

Of course a molecule like BF3 has nonvanishing permanent higher dipole moments, the first being the quadrupole moment. Therefore, not only the polar bonds but the shape of the molecule also determines the molecular polarity. Boron trifluoride (BF3) has no dipole moment (mu = 0D) . DIPOLE MOMENT Let's do two more examples. AX3E2 Molecules: BrF3; Molecules with polar covalent bonds can have a dipole moment, an asymmetrical distribution of charge that results in a tendency for molecules to align themselves in an applied electric field.
