Dipole

Dipole molecule

A dipole is a molecule which has two magnetic poles, caused by a non-zero total magnetic charge. The poles are normally denoted north and south, respectively. Common dipole molecules are water, ozone (but not atmospheric oxygen O₂), and benzene.

As is well known, oil and water do not mix. This is because most or all oil molecules have a different molecular polarity than water.
