Oxidation of acetaldehyde with \(SeO_2\) forms:

Glyoxal

We have to know that acetaldehyde is a natural synthetic compound with the equation \(CH_3CHO\), here and there curtailed by scientific experts as \(MeCHO\). It is perhaps the main aldehyde, happening generally in nature and being delivered for a huge scope in industry. Acetaldehyde happens normally in espresso, bread, and ready organic products, and is delivered by plants. It is additionally delivered by the incomplete oxidation of ethanol by the liver protein liquor dehydrogenase and is a contributing reason for headache after liquor utilization. Pathways of openness incorporate air, water, land, or groundwater, just as drink and smoke. Utilization of di-sulfiram restrains acetaldehyde dehydrogenase, the protein answerable for the digestion of acetaldehyde, accordingly making it develop in the body.

Oxidation of acetaldehyde with selenium dioxide produces glyoxal.

The balanced chemical equation has to be given below,

\(CH_3CHO + SeO_2 \longrightarrow \underset{glyoxal}{CHO–CHO} + Se + H_2O\)
