Abstract
In an earlier communication1 we reported our results on the effect of electron donating substituents on the polarographic reduction of 4-phenylazopyrazole. In this communication we report our results on the effect of an electron withdrawing substituent on the E1/2 of 1-thiocarbamoyl-3, 5-diphenyl-4-phenylazopyrazole. The studies were carried out in non-aqueous medium due to water insoluble nature of these compounds.
