What Is Bond Dissociation Energy?

The bond-dissociation energy 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.

What is meant by bond dissociation energy?

The bond dissociation energy is the energy required—an endothermic process—to break a bond and form two atomic or molecular fragments, each with one electron of the original shared pair. ... A high bond dissociation energy means that the bond (and molecule) is of low energy and stable.

What is bond dissociation energy class 11?

The Bond Dissociation Enthalpy refers to the amount of energy that is required during an endothermic process to break a chemical bond and produce two separated atoms, each with one electron of the first mutual pair.
