The effect of substituents on reduction potentials of para-substituted halobenzenes was compared with that for the corresponding nitrobenzenes, and the effect of substituents on E1/2 value in the series of substituted halobenzenes was analyzed in the framework of Hammett equation. A conclusion drawn there-from permits a statement that at electrochemical reduction of p-iodonitrobenzene, para-substituted bromo and chlorobenzenes with electron-acceptor substituents the additional electron occupies the vacant π-molecular orbital, and in all the other substituted iodobenzenes and also in para-substituted bromobenzenes containing electron-donating substituents the additional electron occupies σ*(C-Hlg) molecular orbital. ©1998 MAHK "Hayka/Interperiodica".
