Birds of feather flock together/When oxygen reacts with the hydrogen from methane to form water, the electrons of the covalent bonds are drawn closer to the oxygen. In effect, each oxygen atom has partially “gained” electrons, and so the oxygen molecule has been reduced. Oxygen is very electronegative, and is one of the most potent of all oxidizing agents.
