A student mixed ethyl alcohol with small amount of sodium dichromate and added to the hot solution of dilute sulphuric acid. A vigorous reaction took place. He disti.... the product formed immediately. What was the product?
Correct answer: D. Acetaltdehyde
- A. Acetone
- B. Acetic acid
- C. Dimethyl ether
- D. Acetaltdehyde
Explanation
If not distilled, aldehyde will be oxidized to corresponding carboxylic acid.So, when the student mixed ethyl alcohol with sodium dichromate and dilute sulfuric acid, something really exciting happened! There was a super energetic reaction, and the product that formed immediately was acetaldehyde. Acetaldehyde is this cool organic compound that's produced when ethyl alcohol (you know, like the kind we drink) gets oxidized. It's a colorless liquid with a strong smell, and it's used in lots of different industries, like making medicines, plastics, and even perfumes.

About Aldehydes and Ketones
Aldehydes and ketones contain the polar carbonyl group, but aldehydes are generally more readily oxidised and more reactive than ketones. Coverage includes preparation by oxidation or reduction routes, nucleophilic addition of reagents such as hydrogen cyanide and bisulfite, and tests that distinguish aldehydes from ketones.
