最近,李朝恩等在 Sanderson 电负性均等原理基础上,提出用逐级均分法计算基团电负性。他们认为,直接键连的基团或与一个
Recently, according to Sanderson’s theory of electronegativity equalization, Li Chaoen et al. Proposed that the grading electronegativity be calculated by the stepwise equalization method. They think that the direct bond with the group or with one
