WebBond energy (E) measures the strength of a chemical bond. Essentially, it is the amount of energy required to break down a molecule into its atoms. Another term for bond energy … WebFeb 7, 2016 · The bond enthalpy is more of an average value than an accurate figure. For example, the energy required to break the first double bond between the central carbon atom and the oxygen is different from the energy required to break the second double bond. This is because the strength of the bond is dependent upon its environment.
