The half-wave potentials and limiting currents for reduction on a dropping mercury electrode were found for the hydrazines. The charge and spin densities of the investigated compounds were calculated by the Hiickel MO and MacLachlan methods. It is shown that in the case of strong interaction with a medium the characteristics of the trinitrophenyl groups of the picrylhydrazines are practically the same, regardless of the structure of the hydrazine residue bonded to them |
