Average Bond Energy Definition:
Average bond energy is a general bond energy value used for a particular bond when the exact bond energy is not required.

Average Bond Energy Notes:
When one mole of a particular bond is to be broken into one mole of gaseous molecule, an energy is required. This energy is called bond energy. A general value used for this energy is called average bond energy. It is also known as bond enthalpy. It is the measure of strength of a bond. The stronger the bond, the more energy will be required to break it. It is usually expressed in units of kJ mol-1, measured at 298 K. It takes roughly 100 kcal of energy to break 1 mol of C-H bonds, so we can say that the bond energy of a C-H bond is about 100 kcal/mol. The bond energies of various bonds are known and calculated and it helps to predict other characteristics of compounds.
