Abstract

The molecular structures of C2H5Cl,C2H3Cl,C2HCl,C4H5Cl,C6H5Cl,and C8H7Cl are optimized by the ab initio methods with 6-311+G** basis set.The bond length,wiberg bond order and the electron density of C-Cl in every molecular are compared.The result shows the relationship of the delocalization of the π bonds with the bond length,wiberg bond order and the electron density of C-Cl in every molecular.
