Electrochemical studies of 4-chloro-3-rritrobenzophenone

Abstract

The electrochemical behaviour of 4-chloro-3-nitrobenzophenone has been studied at dropping mercury electrode (d.m.e.) and hanging mercury drop electrode (HMDE) employing d.c. polarography, a.c. polarography, cyclic voltammetry, chronoamperometry and chronopotentiometry in different supporting electrolytes in methanol-water and DMF-water mixtures. Millicoulometry and controlled potential electrolysis have been used to estimate the number of electrons and to identify the reduction product respectively. Kinetic parameters such as transfer coefficient, diffusion coefficient and heterogeneous forward rate constant values have been evaluated. A reduction mechanism consistent with the data, has been proposed.
