The existence of He + 2 should be predicted. Concept Introduction: According to molecular orbital theory, covalent bonds result when atomic orbitals combine to form molecular orbitals. Minimum energy corresponds to maximum stability. Two atomic orbitals combine to give a bonding MO and a higher energy antibonding MO. Electrons in a bonding MO assist in bonding. Electrons in an antibonding MO detract from bonding. Cylindrically symmetrical bonds are called sigma ( σ ) bonds; side to side overlap of parallel p orbital forms a pi ( π ) bond. Bond strength is measured by the bond Dissociation energy .

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.
