Polarity, polarisability, and association in methyl- and chloro-anilines

Abstract

Dipole moments and molar Kerr constants (×10¹²) are reported for the following as solutes in carbon tetrachloride and benzene: 2,6-dimethylaniline; 3,5-dimethylaniline; 2,6-dichloroaniline; and 3,5-dichloroaniline. The experimental results are used to investigate the polarity and polarisability characteristics of these molecules and, with the aid of ¹H n.m.r. spectroscopy, to examine the incidence of intramolecular and intermolecular associations.
