Abstract:  In this study the Polarographie reduction of ten 2-hydroxybenzophenono derivatives substituted on positions 4 and 5 (/), six 2-hydroxy-5-methylbenzophenone derivatives substituted on positions 3' and 4' (II), and seven 2-hydroxy-6-methylbenzopheiioiie derivatives substituted on positions 3, 4 and 5 (III), has been investigated. This reduction has been investigated in 0.1 M-HCl and 0.1 M-NaOH containing 50 volume % of methanol and in acetate buffer solution containing 40 volume % of methanol. The half-wave potentials of the derivatives (/) and (II) have been correlated to G constants. For each of these two types, the different correlation straight lines were obtained. The steric effect of the methyl group on position 6 of derivatives (III) has become effective by the shift of half-wave potential to more negative values.
