The oxidation reaction of alkyne (ethyne) with alcoholic potassium permanganate produce
Correct answer: B. Oxalic acid
- A. Formic acid
- B. Oxalic acid
- C. Acetic acid
- D. Hydrochloric acid
Explanation
The end product of oxidation of ethyne is Oxalic acid. Alkynes oxidize into vicinal diketones (1,2 diketones) and are then further oxidized into carboxylic acid. For ethyne on oxidation they first form Glyoxal and then Oxalic acid being the end-product of oxidation
