| 中文摘要: |
| 在电负性均衡原理基础上,对逐级加合均分法计算基团电负性公式进行改进,将常用基团的电负性进行重新计算,结果表明新方法不仅能有效区分对称型基团(-XY和-YX)的电负性,而且由此得到的基团电负性与目前被广泛接受的几套基团电负性颇为一致,且呈明显的规律性变化. |
| 英文摘要: |
| According to the principle of electronegativity equilibrium,we revised the formula for gradual sum even way to calculate electronegativities of groups,and calculated some often-used electronegativities of groups by the revised formula in this paper.The calculated results not only conform very much to the several scales of group electronegativities which are widely accepted,but also can distinguish electronegativities of symmetrical groups(-XY and-YX),indicating regular changes. |
