canceling dipoles

Postby Josephine Chan 1B » Sun Nov 25, 2018 8:45 am

in which situations exactly do dipole cancel each other out?

Dipoles would cancel each other out when the polar bonds in a molecule are equal and opposite. Molecules that have symmetry thus often have dipole cancellation.

This can be seen in CO2 as it is a linear shape. In the CO2 molecule, the partial negative oxygens will have a dipole moment outward, effectively cancelling each other out.

I like to think about a molecules shape to determine if there is symmetry or not in the polar bonds. If so, the dipoles cancel out meaning there is no net dipole.
