  • The bond dissociation energy or, more completely, homolytic bond dissociation energy (symbol: BDE) of a covalent bond is the energy required to break the bond homolytically (see homolysis) under standard conditions.

    eg. 1:

     

     

    eg. 2:

     

     

    The bond dissociation energy of a bond is a measure of its strength.  The higher the bond dissociation energy, the stronger the bond.
