Webe) In Hydrogen peroxide (H 2 O 2) the O—H bond pairs are assigned to the more electronegative O’s, but the O―O bond is purely covalent, and the electron pair is divided equally. This gives each O seven electrons, a gain of 1 over the neutral atom. The oxidation numbers are. (4.3.6) H 2 +1 O 2 − 1.
