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...
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:...
In order to predict the geometry of molecules, Nyholm and Gillespie developed a qualitative model known as Valence Shell Electron Pair Repulsion Theory (VSEPR Theory). The basic assumptions of this theory are summarized below.1) The electron pairs in the valence shell around the central atom of ...
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 ...
Valence Shell Electron Pair Repulsion Theory (VSEPR) is a molecular model to predict thegeometryof the atoms making up amoleculewhere the electrostatic forces between a molecule'svalence electronsare minimized around a centralatom. The theory is also known as Gillespie–Nyholm theory, after the two...
VSEPR is such an electrostatic theory of bonding. As with Lewis dot structures, it ignores specific orbitals. The observed geometry reflects the attempt to minimize electron–electron repulsion by maximizing the distance between electrons. Bond angles are determined solely by the number of valence ...
