The molecule in which there exists no separation of charges between the molecule is called a non-polar molecule. So in these cases, no positive or negative poles are formed.
Nonpolar molecules are generally dissolved in nonpolar or mostly organic solvents.
In these molecules, the charge is symmetrically distributed across the molecule.
Examples are carbon dioxide , carbon tetrachloride (), oxygen ( ), nitrogen etc.
Hence, an example of a non-polar molecule is carbon dioxide .
