Abstract:
The polarographic behaviour of three o-hydroxyketoximes, CH(3)C(6)H(3)(OH)CRNOH, where R CH(3), C(2)H(5) and C(3)H(7), has been studied in 5% ethanolic medium, with potassium chloride as supporting electrolyte. A single four-electron reduction wave is obtained which diminishes with increase in pH, being replaced by a new wave in alkaline media. A trough is formed on the limiting-current plateau at higher negative potentials. A mechanism has been proposed for the reduction at the dropping mercury electrode.

Aldehydes readily undergo oxidation in strong oxidizing agents such as potassium permanganate and chromic acid. The oxidation can also be carried out using mild oxidizing agents such as silver oxide. In fact, aldehydes can be easily oxidized...
