摘要
在电负性均衡原理基础上 ,提出了一个新的计算基团电负性公式 :XG={ 1n1 l∑n1 ll=1[1n2 l∑n2 ll=1… (1nkl∑nkll=1Xkl)… ]}用上式计算了 5 2 8个开链基团和环状基团的电负性 ,计算结果与国内外流行几套基团电负性颇为一致 ,且呈明显的变化规律 .
According to the principle of electronegativity equilibrium, a new formula for calculation of group electronegativities has been given X G=｛1n 1l ∑n 1l l=1[1n 2l ∑n 2l l=1…(1n kl ∑n kl l=1X kl )…]｝ The group electronegativities for 528 chain\|groups and cyclic\|groups have been calculated. The results of the present work correspond very well to the several sets of popular graup electronegativities published in literatures.
