10. The bond dissociation energy is the amount of energy required to break a bond A) homolytically B) heterolytically C) so as to produce the more stable pair of ions D) via hydrogenation E) none of the above 11. Energy is when bonds are formed and is when bonds urc broken; therefore, bond dissociation energies are always A) released/ consumed / exothermic B) released/ consumed/endothermic S consumed / released /exothermic D) consumed / released / endothermic E) consumed/released/isothermic Which of the presented mechanisms would be the most energetically favorable and thus the most likely mechanism to actually occur for the following free radical chain reaction? 12) (bond dissociation energies-H-H-104 kcal/mol, Cl-CI = 58 kcal/mol; H-C-103 keal/mol) 112 C22C H. +Cl2 â Cl. + HCl B) C12-vlight â Cl. + Cl.
