H_2O_2、O_2F_2都是含过氧链的分子.根据孤电子对之间的排斥大于孤电子与成链的电子对之间的排斥,大于成键电子对之间的排斥的价电子对互斥理论,要使过氧链上两个氧原子的四对孤电子之间的排斥最小,必须使四个原子处于同一平面上,两个氢原子或F原子处于反式,即反式共平面.但实际上,它们都是非平面反式结.构.见图(一)和表(一)其原因何在?这主要是由于它们分子内部其它成键作用所致.
Both H 2 O 2 and O 2 F 2 are molecules containing a peroxo-chain. According to the exclusion between lone pairs of electrons, which is larger than the exclusion between lone pairs of electrons and chains, the exclusion of valence electron pairs , In order to minimize the repulsion between the four pairs of lone electrons of the two oxygen atoms in the peroxidic chain, four atoms must be in the same plane, and two hydrogen atoms or F atoms are trans-trans coplanar. In fact, they are all non-planar transformers. As shown in Figure 1 and Table 1, what are the reasons for this? This is mainly due to other key interactions within their molecules.
