If we break up the #C-H# bonds we get #2xxH^+#, and #{C-=C}^(2-)# (carbon is more electronegative than hydrogen, so when you (for the purposes of assigning oxidation number) break this bond you put a formal #+1# charge on hydrogen, and a formal #-1# charge of carbon. Keep in mind that each carbon was supposed to have an oxidation state of minus two, so if we look over here at the carbon on the left, and we just assign those electrons really quickly, we can see that that would be the same caluclation, four minus six gives us minus two, so each carbon has an oxidation state … The oxidation state of carbon in the compounds {CH}_{4},{C}_{2}{H}_{6} and {C}_{2}{H}_{2} is +4 . ...

Oxidation state assignments are of course formalisms; they do not have real significance other than what we assign for them. The hydrogen atoms all have oxidation state +1, because they surrender their electron to the more electronegative atoms to which they are bonded. The concept of oxidation number doesn't apply because each carbon has the same electronegativity.
