WebbThis extra oxygen atom is described as a “peroxidic oxygen” and is otherwise known as “active oxygen.”. Hydrogen peroxide has the ability to oxidize some compounds directly; for instance, alkenes, as shown below. The peroxidic oxygen adds to the double bond, producing a hydroperoxide, as shown in equation 7-19. The boiling point of H2O2 has been extrapolated as being 150.2 °C (302.4 °F), approximately 50 °C (90 °F) higher than water. In practice, hydrogen peroxide will undergo potentially explosive thermal decomposition if heated to this temperature. It may be safely distilled at lower temperatures under reduced pressure.
