以角锥化方式变形可以明显降低能量，再加之平面结构位阻不小，所以采取三角锥构型，N采取sp³杂化态。

增强分子的稳定性。此外，三硝基胺的N-N-N键角为108.1°，这也符合sp2杂化的特点。
Bond dissociation energy (BDE) is a quantitative descriptor of the strength of chemical bonds, providing useful information for understanding molecular stability [1]. As for energetic compounds, many indicators of safety properties, such as impact sensitivity [2], shock sensitivity [3] and thermal ...

In HO(NO2) there are 5 atoms sharing 4 bonds for which we need to assign the electrons in order to find the oxidation numbers. Once you have drawn the lewis diagram for HO(NO2), you can look at each bond and assign its electrons to the more electronegative species. Bonds in HO(NO...
