价层电子对互斥理论及应用

Valence shell electronrepulsion theory and its applications

叙述了价层电子对互斥理论的基本规则 ;计算出价层电子对数 ,得到电子几何排布 ,从而判断出分子的几何构型 ;

The basic formula of valence shell electronie Repuleion theory are depicted. Calculating the number of valence electron shell,we can gain the geometry array of the electron, then judge the geometry configuration of molecule; By the way,the effect on the geometry configuration of molecule and its bond angels are introduced when lone electron pairs exist.
