Dipole Moments

Postby Hannah Faris 1C » Sat Nov 10, 2018 10:05 pm

Does anyone know if we would ever have to calculate anything like a dipole moment? It might have been said in class but I just can't remember at all.

Thanks so much!

I'm pretty sure don't have to calculate them!

He said that we definitely won't have to, but knowing the equation for the sake of conceptual questions is probably a good idea.

Which was the equation given for dipole moments?

What exactly is a dipole moment? I know it was to do with charges, but is there a deeper explanation?

A dipole moment occurs when one atom in a molecule (or one side of a molecule) is more electronegative than the other, meaning that it attracts electrons. This attraction causes a net negative charge on one end of the molecule and consequently a positive charge on the other end. This polarity within the molecule affects how it bonds with other molecules.

The equation given for dipole moments was:
dipole moment= charge x distance between atoms (bond length)

Can someone please explain the difference between an induced dipole, dipole moment, and dipole-dipole interaction? When would you observe one versus the others?

An induced dipole is when a molecule that is usually non polar has become temporarily induced to have a dipole by surrounding molecules. I believe a dipole moment is just when a molecule itself has a dipole due the electronegativity of its constituent atoms. A dipole-dipole interaction is when any polar molecule has an interaction with another polar molecule.

A dipole-dipole interaction occurs when two polar molecules interact. The partially positive side of one molecule is attracted to the negative side of the other molecule. This is different from a dipole-induced dipole interaction because in a dipole-induced dipole interaction, a polar molecule induces a dipole of an otherwise nonpolar molecule. This happens because the polar molecule distorts the electrons on the nonpolar molecule, resulting in a weak attraction between the two molecules. A dipole moment measures the separation between opposite charges. Hope this helps!
