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 ...

The polar part of alcohol is attracted to and interacts with polar water molecules and causes alcohol to dissolve. The polar parts of the glucose molecule are attracted to and interact with water and ...

The largest group of amino acids have nonpolar side chains ... Charged amino acid side chains can form ionic bonds, and polar amino acids are capable of forming hydrogen bonds.
