2.4d: carry out experiments to determine the effect of an electrostatic force on jets of liquids and use the results to determine whether the molecules are polar or nonpolar

1. Rub a glass or polythene rod with a cloth to build up electrostatic forces
2. Hold the charged rod next to the stream of liquid from a burette
3. If the liquid is deflected, it is polar (eg. water, hexene), if not, it is non-polar (eg. hexane)
