Breaking carbon oxygen bonds
WebCarbohydrates are biological molecules made of carbon, hydrogen, and oxygen in a ratio of roughly one carbon atom (C \text C C start text, C, ... Because it requires breaking off the bonds. If you want to turn H, and OH into one another, you will have to break bonds and reattach them. This does not happen spontaneously in water. 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.
