CH4, also known as the molecule methane, is nonpolar. The covalent bonds in methane are nonpolar because the sharing of electrons in the bonds are equal.
According to About.com, molecules with nonpolar covalent bonds do not have a dipole moment because the sharing of charges is equal. Polar molecules do have a dipole moment, where the molecule has a positive and a negative end, because the sharing of electrons between atoms is unequal. Methane is composed of one carbon atom and four hydrogen atoms. The molecular formula for methane is CH4. Nonpolar molecules are not able to interact with water, making the molecules hydrophobic, or water fearing.
