By comparing the bond energies of the given bonds to that of C-H bond, it is to be verified that halogens and peroxides have weak bonds. Concept introduction: The energy that would be required to increase the distance between two bonded atoms from the bond length to infinity, that is, breaking of one mole of molecules into their individual atoms, is termed as the bond energy. The larger value of bond energy represents strong 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.

refer to image please please label graph and show all work. CALCULATE R VALUE AND EXPLAIN. will only rate if graph is labelled. label name of structure too.

Draw two other possible resonance structures and the mechanism arrows to get from one to the next. You will have to draw any lone pairs that you use. Also you have to go from one contributor to the next in a linear fashion meaning that one structure should not be used to get to two different contributors. Lastly circle the major contributor(s). There are actually five contributors but you just have to draw two.

I already know this is a schmdit reaction, I need to know what extact bonds are broken formed please :)))
