The Complexes of Chlorobenzene with Halogens and Interhalogens in Carbon Tetrachloride

[摘要] The results of ultraviolet spectrophotometric investigations on the system of chlorobenzene with iodine, chlorine and iodine monobromide in carbon tetrachloride at 25¡Æ indicate the formation of one to one molecular complexes, C6H5Cl¡¤I2, C6H5Cl¡¤Cl2 and C6H5Cl¡¤IBr. The equilibrium constants obtained at 25¡Æ for the complex formations are 0.106, 0.0400 and 0.109 lmole-1, respectively. These results combined with those reported in the literature reveal the following order as the relative stabilities of complexes with aromatics and with halogens or interhalogens, respectively. ICl > IBr > I2 > Br2 > Cl2. Benzene > Chlorobenzene.
