The C-H bonds of Trans-3-hexene are to be ranked in the order of decreasing bond dissociation enthalpy. Concept introduction: Bond dissociation enthalpy is the amount of energy required to break a covalent bond. The stronger the bond, the higher the bond dissociation enthalpy. The C-H bond in alkenes is stronger than the C-H bond in alkanes. The sp 2 -hybridized carbon atoms have stronger C-H bonds than C-H bonds in sp 3 -hybridized carbon atoms. Allylic C-H bonds are weaker than non-allylic (alkyl) C-H bonds.

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.
