Ethyne on oxidation with alcoholic KMnO4 forms _
Correct answer: B. Oxalic acid
- A. Hydrochloric acid
- B. Oxalic acid
- C. Acetic acid
- D. Formic acid
Explanation
The correct answer is Oxalic acid. Alkynes oxidize into vicinal diketones (1,2 diketones) and are then further oxidized into carboxylic acid. For ethyne, the end product of oxidation is Oxalic acid. This process involves the formation of Glyoxal before reaching the final product. The other options are incorrect because they do not align with the oxidation products of ethyne and have different carbon structures or functional groups.
