Each of them exhibited sensitive reduction responses of nitryls. It was found that the reduction peak of nitryl of the position 4-nitrate group of 2,4-dinitrophenol showed great difference from that of the position 5-nitrate group of 2,5-dinitrophenol. The difference between the two reduction potentials was as large as 180 mV.
