一个制定杂化轨道类型的规则

A CRITERIOR RULE FOR THE TYPEOF HYBRID ORBITALS

本文提出了一个判断中心原子杂化轨道类型的经验规则：杂化轨道数Ｎ＝Ｖ２－３ｎ＝２，３，４，５，６时，分别为ｓｐ，ｓｐ２，ｓｐ３，ｓｐ３ｄ和ｓｐ３ｄ２杂化．式中Ｖ是中心原子价电子总数，ｎ是非氢原子配位数．该规则具有适用范围较广且较简捷的优点．

An empirical rule for determing the hybridization type of central atomic orbitals was proposed, which is N=V2-3n(N: number of hybrid orbitals, V :number of valence electrons, n: number of atoms accept hydrogen). when N =2,3,4,5 and 6,the hybrid orbitals will be the sp, sp 2, sp 3, sp 3d and sp 3d 2 respectively. This rule has advantages of simple and direct, and has wide applicable range as well.
