Can someone explain permanent dipole moments to me please? As well as their importance

Permanent Dipole Moments occur when the difference in the electronegativity of two atoms in a molecule is large. The more electronegative atom will attract more electrons, thus creating a partial negative charge around that atom and a partial positive charge around the atom with the lower electronegativity. Molecules with permanent dipole moments are just polar molecules, as opposed to having dipole moments that are induced by other molecules. They are important because the polarity of a molecule determines many of its properties and how it interacts with other molecules. Hope this helps!

A permanent dipole moment is when the molecule is polar. The two or more atoms within the molecule must have substantially different electronegativities (one must attract electrons more than the other and becomes more negative while the other becomes positive).

A permament Dipole moment is when the difference of electronegativity between two atoms is so large that it holds a partial positive and partial negative charge. Hope this helps! :)

Is there some kind of a cutoff for how to decide whether or not a dipole is permanent?
