5. Which of the following statements regarding the reactions A and B (shown below) is the best? 0 heat 0 heat B A . Both reaction A and B are feasible because frontier orbitals of reactants can overlap in-phase, allowing the simultaneous formation of two o bonds. . Both reaction A and B are NOT feasible because frontier orbitals of reactants can NOT overlap in-phase. Only reaction A is feasible because frontier orbitals of reactants can overlap in- phase, allowing the simultaneous formation of two o bonds. Only reaction B is feasible because frontier orbitals of reactants can overlap in- phase, allowing the simultaneous formation of two o bonds.
