WebThe breaking of chemical bond is called bond cleavage. There are two types of bond cleavage depending on the sharing of electrons between the two atoms of the bond. 1. Homolytic cleavage: The two electrons in bond equal shared between the two atoms. 2. Heterolytic cleavage: one of the atoms gets both the electrons of the bond. 2. WebBond cleavage is also possible by a process called heterolysis. The energy involved in this process is called bond dissociation energy (BDE). [2] BDE is defined as the " enthalpy (per mole ) required to break a given bond of some specific molecular entity by homolysis," symbolized as D .
