THEORETICAL STUDY TO THE ELECTRONIC PROPERTIES IN 4-X-1,2-BENZOQUINONES SUBSTITUTED

Abstract

This paper discusses global descriptors such as hardness, electronegativity, nucleofilia and chemical potential and local reactivity indexes. We use the method of the density functional (DFT) to a level of calculation B3LYP/6-31G. With local reactivity indexes analyzed the nucleophile/electrophile character by the effect of substituents on the system 1,2-benzoquinone. With global descriptors of reactivity, we obtained acceptable correlations as well as the effect of substituents on the Uv-vis spectrum groups.
