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.
I have some reactions here for which I need to predict the products. Can you help me solve them and rewrite the equations, as well as identify the type of reaction?

Will this convert the C=O to an alcohol? Or does its participation in the carboxy group prevent that from happening?
