The difference in electronegativity between adjacent atoms participating in a covalent bond drives the formation of a polar molecule. Water molecules are polar and their interaction with each other, via the partial positive and partial negative ends of the molecule, can create very interesting physical properties within a large body of water. Surface tension is a result of this strong interaction between the poles of neighboring water molecules at the water-surface interface. What if we could make different liquids have increased surface tension like water? Which liquids would you choose to increase their surface tension and why?
