Which of the Following Molecules Are Nonpolar?

Nonpolar molecules include hydrogen and oxygen gas, methane and gasoline. Alkynes are also considered nonpolar. Generally, nonpolar compounds are considered water insoluble and do not dissolve in water.

Nonpolar bonds are formed when two atoms share an equal number of electrons, or because of an arrangement of symmetrical polar bonds in complex molecules. Common household examples of nonpolar compounds are oil and fat. Because they do not dissolve in water at room temperature, they are considered hydrophobic. Nonpolar molecules typically have a lower boiling point than polar molecules. Some molecules, called hybrids, are polar on one end and nonpolar on the other.
