Dipole induced-dipole

Postby Miriam Sheetz 2B » Fri Nov 09, 2018 2:15 pm

What exactly is a dipole induced-dipole and how do they happen?

A dipole - induced dipole is when 2 compounds, one of each kind (such as HCl which has a dipole moment and N2 which does not), are attracted to one another. N2 has a lone pair of electrons on each N atom, which is slightly negative, but not strong enough to have a dipole moment. When the slightly negative charge of one N is paired with the positive dipole of one H (from HCl), there is an induced dipole and the molecules attract, therefore resulting in a dipole - induced dipole interaction.

these are also instantaneous attractions bc the induced dipole comes from a momentary fluctuation in an atom's electron cloud.
