Why is methane, CH4, a nonpolar compound?
The molecule methane has four Carbon-Hydrogen single covalent bonds. These covalent bonds are called nonpolar covalent bonds because. The consequence of this equal sharing of electrons is that there is no charge separation (dipole moment).
The example of the compound or the molecule that forms a non-polar bond is oxygen gas.
Oxygen gas has a formula of O₂Since this is a homonuclear molecule, the two bonding atoms have the same kind of electronegativity. The difference is therefore zero. In such a molecule, there is equal sharing of the electron pair between the atoms and no electrostatic charge on the molecule.
