Abstract
The polarographic half-wave potentials of a number of β-nitrostyrenes, β-nitropropenylbenzenes, and β-nitrobutenylbenzenes have been determined in aqueous ethanolic solution at an apparent pH of 6.54. A linear relationship exists between these values and Hammett sigma constants, but not with their ultraviolet absorption maxima or with their dipole moments.The polarographic wave of 11 diethyl benzalmalonates, under the same conditions, was masked by the hydrogen wave.Keywords
