Meanwhile, most of the methods to impr… WebThe bond-dissociation energy ( BDE, D0, or DH°) is one measure of the strength of a chemical bond A−B. It can be defined as the standard enthalpy change when A−B is cleaved by homolysis to give fragments A and B, which are usually radical species. [1] [2] The enthalpy change is temperature-dependent, and the bond-dissociation energy is ...
