With an assumption that initiation is by an unspecified radical, R a reaction radical chain mechanism has to be proposed. Concept Introduction: Halogenation of alkanes : The replacement of one or more hydrogen atoms by halogen. When alkanes is heated or irradiated with the light of specific wavelength, the alkyl halide are formed by radical chain reaction. Radical chain reaction: Initiation reaction: Chain propagation: Chain termination: Bond dissociation energy is a measure of bond strength in a chemical bond . It is a change in enthalpy of a hemolysis reaction at absolute zero where a molecule is broken down into two free radicals.

Answer 1

Question

Formula Formula Bond dissociation energy (BDE) is the energy required to break a bond, making it an endothermic process. BDE is calculated for a particular bond and therefore consists of fragments such as radicals since it undergoes homolytic bond cleavage. For the homolysis of a X-Y molecule, the energy of bond dissociation is calculated as the difference in the total enthalpy of formation for the reactants and products. X-Y → X + Y BDE = Δ H f X + Δ H f Y – Δ H f X-Y where, ΔHf is the heat of formation.
