The Complexes of Bromobenzene with Halogens and Interhalogens in Carbon Tetrachloride

[摘要] The systems of bromobenzene with chlorine and iodine monobromide in carbon tetrachloride have been investigated at 25¡Æby means of ultraviolet spectrophotometric measurements. The results indicate the formation of one to one molecular complexes, C6H5Br¡¤Cl2 and C6H5Br¡¤IBr, in solution. The equilibrium constants obtained at 25¡Æfor the formation of these two complexes are 0.0485 and 0.183 l¡¤mole-1, respectively. Comparison of these results with those reported in the literature on other complexes of similar type shows that the relative stabilities of the complexes decrease in the following orders: ICl > IBr > I2 > Br2 > Cl2 Benzene > bromobenzene > chlorobenzene.
