Question

Butanone on oxidation with K Cr202 + H2SO4 gives: (a) Acetic acid (b) Butanoic acid (c) Propanoic acid and Methanoic acid (d) 2-butanol​

Answer 1

Butanone  on oxidation with $KCr_{2} O_{2}$ + $H_{2}SO_{4}$ gives  (a) Acetic acid.

• Butanone  on oxidation with $KCr_{2} O_{2}$ + $H_{2}SO_{4}$ gives Acetic acid.
• Acetic acid, having the chemical formula CH3COOH, is an organic substance that is acidic and colourless. Aside from water and other trace ingredients, vinegar contains at least 4% acetic acid by volume, making acetic acid its primary ingredient.
• After formic acid, acetic acid is the second-simplest carboxylic acid. It is a significant chemical reagent and industrial chemical produced largely for the creation of synthetic fibres and fabrics, polyvinyl acetate for wood glue, and cellulose acetate for photographic film.
• Acetic acid in diluted form is frequently used in homes as descaling agents. Acetic acid is regulated by the food additive code E260 in the food sector as a condiment and an acidity regulator. The acetyl group, which is produced from acetic acid, is essential to all forms of life in biochemistry. It is essential for the metabolism of lipids and carbohydrates when linked to coenzyme A.

Hence, Butanone  on oxidation with $KCr_{2} O_{2}$ + $H_{2}SO_{4}$ gives  (a) Acetic acid.
