The electrochemical reductions of p-bromo-, p-chloro- and p-nitro-phenacyl bro­mides have been carried out using the techniques of cyclic voltammetry and chrono­potentiometry at hanging mercury drop electrode. Comparative account of their behaviour in different supporting electrolytes studied is presented. Reduction mecha­nism is discussed. The kinetic parameters such as forward rate constants and diffu­sion coefficients evaluated for the reduction process are reported.
