WebNext, we do the same thing for the bond enthalpies of the bonds that are formed. So the bond enthalpy for our carbon-oxygen double bond is 799 kilojoules per mole, and we multiply that by four. The bonds enthalpy for an oxygen hydrogen single bond is 463 kilojoules per mole, and we multiply that by six. When we add these together, we get 5,974. http://research.cm.utexas.edu/nbauld/unit5_radicals.htm
