Solution

Nonpolar Molecule

A nonpolar molecule is a molecule which has no separation of charge, so no positive or negative poles are formed. In other words, the electrical charges of nonpolar molecules are evenly distributed across the molecule. Nonpolar molecules tend to dissolve well in nonpolar solvents, which are frequently organic solvents.

When atoms bond together to form molecules, they share or give electrons. If the electrons are shared equally by the atoms, then there is no resulting charge, and the molecule is nonpolar.


Examples of homonuclear nonpolar molecules are oxygen (O2), nitrogen (N2), and ozone (O3). Other nonpolar molecules include carbon dioxide (CO2) and the organic molecules methane (CH4), toluene, and gasoline. Most carbon compounds are nonpolar. A notable exception is carbon monoxide, CO.
