Following the same rules, the carboxylic acid carbon atom has an oxidation state of +3 (it only gets one valence electron from the C–C bond; the oxygen atoms get all the other electrons because oxygen is more electronegative than carbon). Find the oxidation state of carbon in formic acid , acetic acid , acetelene(C2H2) , ethene and methane. In C2H2 each C has an oxidation state of -1 and each H has an oxidation state of +1. The hydrogen atoms all have oxidation state +1, because they surrender their electron to the more electronegative atoms to which they are bonded. Also, 1 electron is gained from its bond with the other carbon atom because the electron pair in the C–C bond is split equally, giving a total of 7 electrons.
