A substance that contains polar covalent bonds may not be overall polar. This is due to the shape of the molecule. Water molecules are polar molecules. Both of the bonds inside the molecule are ...

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.

When a charged object such as a rubber balloon is brought close to a fine stream of a polar liquid, the stream is attracted toward the electrical charge. If the same charged object is brought close to ...

This creates a tighter arrangement of molecules at the surface and the round shape of a drop of water. Alcohol has one O–H bond which is polar, but a large portion of the molecule is made up of C–H ...
