Water molecules are polar molecules ... This means that the molecule itself is non-polar due to symmetry.

Opposite polar ends of molecules attract and hold one molecule to another. Alcohol has one O–H bond which is polar, but a large portion of the molecule is made up of C–H bonds which are nonpolar.

A new theoretical framework has been developed that achieves remarkable accuracy in predicting binding energies, particularly for polar and nonpolar molecules, which has implications for positron ...
