Dipole Moments

Postby Sydni Stewart » Tue Nov 27, 2018 12:49 am

How do we know when a compound has a dipole moment? Do they all have one?

Not all molecules have a dipole moment. They can only occur if there is a significant difference in electronegativity between two atoms. For a non-polar molecule the dipoles cancel each other out thus not inducing any particular electrical attraction towards one end or the other. While polar molecules have dipoles; one side would be more particularly negative and the other more positive. Arrows pointing towards the more negative element showcases dipole moments.
