WebJun 29, 2016 · On the Pauling scale, we can quote the electronegativities of C,H, and O as 2.55,2.20,3.44. The means that the oxidation number of C in methane, CH 4, is −I V, and the oxidation number of C in carbon dioxide, CO2 is +I V. Note that the SUM of the oxidation numbers equals the charge on the ion. WebNaBH 4 is a source of hydride (H-) and the reaction begins with the addition of hydride to the carbonyl to the aldehyde (Step 1, arrows A and B). Upon addition of acid, the oxygen is protonated (Step 2, arrows C and D) to give the neutral primary alcohol. Notes: The choice of H 2 O / H 2 SO 4 as acid isn’t crucial – this is just an example.
