关于键能、键级、能态与分子的化学活性的关系,目前还存在一些较模糊的看法。例如,有人认为键能越高,则含有该键的分子越稳定。进而认为键极越高,分子越稳定。从概念上说,键能是使某化学键断裂成为基态原子或自由基所需要的能量(以1摩尔化学键计算),它主要反映在分子热稳定性方 There are still some obscure opinions about the relationship between bond energy, bond order, energy state and chemical activity of molecules. For example, one thinks that the higher the bond energy, the more stable the molecule containing the bond. Then think that the higher the key, the more stable molecules. Conceptually, bond energy is the energy required to break a chemical bond into a ground state atom or radical (calculated as 1 mole of chemical bond), which is mainly reflected in the molecular thermostability
