That's an urban legend that's been around for a long time.
It was tested on "Mythbusters". The conclusion was that

A denser liquid will sink to the bottom while a less denser liquid will float. Also, liquids composed of polar molecules such a water will not form chemical <span>bonds with nonpolar molecules.
Density.
