Do dipole moments exist even when there is 0 Formal Charge?

Well if you take the lewis structure of say a water molecule. The formal charges of the two Hs and the O are all zero, but a dipole moment still exists between the partial negative and partial positive charges.

There is dipole moment when the electronegativity difference is big enough, and when the structure is not symmetrical

There may be dipole moments in all types of bonds. Some non polar bonds may have a small dipole, but not a large enough difference in electronegativity that one atom donates all i's electrons to another. Just an unequal sharing of electrons that result in a slightly positive and negative charge.
