Bond Enthalpy Definition:
Bond enthalpy is the energy needed to break one mole of a particular bond in 1 mole of gaseous molecules.

Bond Enthalpy 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 enthalpy. It is also known as bond energy. 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 enthalpy of a C-H bond is about 100 kcal/mol. The bond enthalpies of various bonds are known and calculated and it helps to predict other characteristics of compounds.
