Which among the following product is formed when ethyne undergoes reaction with HgSO4 and H2SO4
Correct answer: C. Acetaldehyde
- A. Formic acid
- B. Formaldehyde
- C. Acetaldehyde
- D. Acetic acid
Explanation
When ethyne reacts with HgSO4 and H2SO4, it forms acetaldehyde, which is a two-carbon aldehyde. This is because ethyne is a two-carbon compound. Other alkynes with more than two carbons would give ketones in the same reaction conditions. Therefore, the correct answer is Option C: Acetaldehyde.
