The polarographic behavior of alkyl hydroperoxides was studied. <I>n</I>-Propyl, <I>n</I>-butyl, <I>n</I>-hexyl, and <I>n</I>-octyl hydroperoxide in an aqueous solution all show diffusion-controlled irreversible waves. The effect of the pH on the <I>E</I><SUB>1⁄2</SUB> and <I>n</I>α values is very small. The length of the alkyl group has a marked effect on <I>E</I><SUB>1⁄2</SUB> and <I>n</I>α. The longer the chain length of the alkyl group, the larger the value of <I>n</I>α and the more positive the <I>E</I><SUB>1⁄2</SUB>. The linear free-energy relationship was found for the four alkyl hydroperoxides examined. The relation of Taft's polar substituent coefficient to <I>E</I><SUB>1⁄2</SUB> has a negative reaction constant, which indicates a reaction promoted by high electron density in the reactive group. The electrode process seems to be the rupture of the –O–O– bond, followed by the protonation of the ions produced on the electrode.
