Among Li 2 and Be 2 , the molecule which will have the greater dissociation energy has to be predicted on the basis of their ground-state electronic configuration. Concept introduction: One of the most useful parameters to discuss the characteristics of bonds is the bond order. The bond order is directly related with the bond length and strength of the bond. Higher the bond order, shorter will be the bond. The bond dissociation energy determines the strength of a bond.

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.
