Valence Shell Electron Pair Repulsion (VSEPR) Theory搜索 Molecular GeometryMolecules of different subtances have diverse shapes. Atoms attach to one anotherin various geometric arrangements. The overall molecular shape of a molecule isdetermined by its bond angles in three dimensions. The shape of a ...
阅读下面的材料并思考价层电子对互斥理论(Valence Shell ElectronPair Repulsion Theory)适用于主族元素间形成的AB_n 型分子或离子。该理论认为,一个共价分子或离子中,中心原子A周围所配置的原子B(配位原子)的立体构型,主要决定于中心原子的价电子层中各电子对间的相互排斥作用。这些电子对在中心原子周围按尽可能互相...

1940年美国的 Sidgwick等人提出了价层电子对互斥理论(valence shell electron pair repulsiontheory),简称 VSEPR法。对于 AX。型分子或离子,其价层电子对指的是中心原子形成σ键的电子对和孤对电子对,其数目等于X原子数n与孤对电子对数之和。该理论认为,AX。型分子或离子的几何构型,主要决定于中心原子的价层电子...
Bond angles are determined solely by the number of valence electrons around a central atom. It is instructive to use examples…doi:10.1002/0470845015.cvd002Chemical bondJohn Wiley & Sons, Ltd
Valence-shell electron-pair repulsion (VSEPR) theory is conventionally used to predict molecular geometry. However, it is difficult to explore the full implications of this theory by simply drawing chemical structures. Here, we introduce origami modelling as a more accessible approach for exploration ...
Valence shell electron pair repulsion, VSEPR, is a super-simple technique for predicting the geometry of atomic centres in molecules and molecular ions: Crucially, atomic centres with VSEPR determined geometry can be joined together into molecular entities like cyclohexane and glucose:...
