The research on the electronegativity for methyl in different molecular environment

Abstract

The paper supposed a method for calculating the electronegativities of methyl in different molecular environment. The electronegativities scale of methyl in some common different molecular environment were calculated. The results indicate that the methyls in different molecular environments have a different parameters of inductive effect. These parameters of inductive effect of methyls exhibit markedly their periodic rule and can be used in discussing quantitative structure-activity relationships (QSAR).

Key words: INDUCTIVE EFFECT, STRUCTURE AND PROPERTY CORRELATION, CORRELATION ANALYSIS, MOLECULAR MODEL, CARBON ATOM, ELECTRONEGATIVITY, METHYL GROUP
