Quick Summary

A nonpolar molecule is a molecule that has no net electrical charge, meaning its positive and negative charges are arranged symmetrically. This occurs when bonds between atoms are electrically uniform, such as in molecules composed of identical atoms like H2 or Cl2. Even if a molecule contains polar bonds (bonds between atoms of different elements with unequal sharing of electrons), the molecule as a whole can be nonpolar if its shape causes the bond dipoles to cancel each other out. For example, the linear molecule carbon dioxide (CO2) has polar carbon-oxygen bonds, but its symmetrical structure results in a nonpolar molecule. Nonpolar molecules are generally lipophilic, meaning they dissolve in lipids or nonpolar solvents.123
