The solution dipole moments and the atomic polarizations of chloro-, bromo-, and iodo-benzenes

Abstract

Dielectric constant and density measurements of solutions of chloro-, bromo-, and iodo-benzene together with those of p-dichloro-, p-dibromo- and p-diiodo-benzene in carbon tetrachloride at 25º are given. Distortion and atomic polarization values for the polar solutes are estimated by a method proposed by Böttcher; the values are compared with other estimates of P_D and P_A. To obtain quantitative information of atomic polarizations, using Böttcher's method, greater precision than is usual in solution dielectric constant measurements would be required.
