Glyoxal formed by loss of two water molecules by tetrahydroxy ethane oxidizes to
Correct answer: C. Oxalic acid
- A. Ethylene glycol
- B. Acetylene
- C. Oxalic acid
- D. Benzoic acid
Explanation
When tetrahydroxy ethane oxidizes, it forms glyoxal, which further oxidizes to oxalic acid. This is because oxidation is the addition of oxygen, and the number of carbon atoms remains the same in this process. The other options are incorrect because they do not align with the oxidation products of glyoxal or the starting compound tetrahydroxy ethane.
