Bond-dissociation energy

Bond-dissociation energy (BDE) is defined as the energy required to break a specific bond in a molecule in its gaseous state, leading to the formation of two separate, neutral radical fragments. It is a measure of the strength of a chemical bond; the higher the bond-dissociation energy, the stronger the bond. BDE is typically reported in units of kilojoules per mole (kJ/mol) or kilocalories per mole (kcal/mol).
