Dipole Moment
Does electronegativity have to do with a dipole moment? Are we supposed to know how to calculate a dipole moment on a test?
Re: Dipole Moment
A dipole moment happens when there is a separation of partial charges within a molecule, which happens when there is a big difference in electronegativity. For example, in H20, there is a dipole moment pointing towards oxygen because oxygen has a much higher electronegativity than hydrogen.

Re: Dipole Moment
I don't think we will have to calculate any values concerning dipole moments on a test, but I am pretty sure that we will have to recognize and identify which molecules participate in dipole moments with each other by determining relative electronegativity within their atoms.

Re: Dipole Moment
Furthermore, the dipole moments help us figure out if a molecule is polar or non polar. This classification will allow us to figure out what type of bonds/intermolecular forces are present within a molecule. For example, if the dipole moments do not cancel, the molecule is polar. A non polar molecule, on the other hand, will have a zero electric dipole moment where the dipole moments cancel.
