Dipole Moment

[Riya Sood 4G]

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

[SarahSteffen_LEC4]

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.

[Kellylin_4D]

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

[Megan_1F]

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.
