Dipole Moments

Postby Victoria Luu - 1C » Sat Nov 10, 2018 4:16 pm

Hi!
I was wondering how you can tell which atom has which dipole moment, and how a dipole moment works.

It has to do with the electronegativity difference between atoms. Molecules with atoms of same electronegativity have no dipole movement whereas a molecule such as HF has dipole movement due the electronegativity difference.

Dipole moments develop due to variances in electronegativity. The atom that is more electornegative has a negative value, and less electronegative is positive value. The direction can be shown by drawing an arrow from positive to negative atom, since the negative atom pulls electrons towards itself due to its greater electronegativity.

Dipole moments are due to the differences in electronegativity between the two atoms. the more negative atom will pull the electrons of the positive one toward it, causing a dipole moment.

Basically molecules with atoms that differ largely in terms of electronegativity should have dipole moments
