When do you calculate a dipole moment? How do you know if a compound has a dipole moment?

We don't particularly calculate dipole moments, but they occur primarily when there is two atoms with differing electronegativities bonded together. I can develop more if necessary, hope this helps!

Basically, as long as the two atoms bonded together are not the same element, there will most likely be a dipole moment between them. In terms of calculating the dipole moment between two atoms, I think you might want to do it when determining the structure of a complex molecule where various dipole moments can really make a difference in the final shape of the molecule.

Hope this can help!

How do we know when a molecule has a dipole moment?

All molecules have some sort of dipole-dipole interaction (which is the van der Waals' forces that we discussed in class)

I think most molecules have some sort of a dipole-dipole force. It depends on factors like bond symmetry and electronegativity difference.

A dipole moment is essentially just the difference in charges between different atoms in a compound. This is typically found by comparing each atom's electronegativity to each other.
