Negative Pole

Postby KMcFarland_2L » Wed Nov 25, 2020 2:43 pm

How do you approximate where the negative pole is on a molecule?

You would look at the electronegativity of the atoms. The most electronegative would be the more negative pole of the dipole moment.

The dipole moment always points towards the more electronegative element. So, you can either just identify the more electronegative element or use the arrow to identify it.

You should also consider if any dipole moments cancel out. For example, if it is a symmetric linear molecule with negative dipoles on both sides of the central atom, the atom as a whole would actually not be polar.

Considering the Lewis and VSEPR model for compounds helps a lot in this regard because it depicts the direction of atoms' pull on electrons, so it's easier to see if two dipole moments cancel.

Hi! After making sure multiple dipoles aren't cancelling each other out, the more electronegative element will be the negative pole of the dipole.

If you do not draw the structure correctly, would you still be able to figure out if you have a negative and or positive pole?

Determining the negative pole is dependent on the dipole moment present between the two elements, which is dependent on the electronegativity, and its magnitude is related to their overall difference in electronegativity.
