Bond Energy Definition

Bond Energy Explanation

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. 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.
