Nonmetals don’t have enough electronegativity to transfer electrons so the electrons are shared between them
Fractional Distillation is the answer
The chemical bonds in CH4 are all single bonds. C only can bond 4 times because it needs 8 electrons in it's outer shell and only has four right now. The bonds represented are all single bonds because there are two electrons present on each side of the carbon. Two electrons, in this case, equals one bond.
