Question:
The product of hydrolysis of propyne in the presence of 1% \( HgSO_4 \) and 40% \( H_2SO_4 \) is ___________.
The product of hydrolysis of propyne in the presence of 1% \( HgSO_4 \) and 40% \( H_2SO_4 \) is ___________.
Show Hint
The hydration of alkynes, like propyne, often results in ketones due to the Markovnikov's rule and subsequent keto-enol tautomerism.

- methanal
- ethanal
- propanal
- propanone
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
When propyne \( (CH_3 - C \equiv CH) \) is treated with 1% \( HgSO_4 \) and 40% \( H_2SO_4 \), it hydrates according to Markovnikov's rule, initially forming an enol that subsequently tautomerizes into propanone \( (CH_3 - CO - CH_3) \), the most stable keto form.
Therefore, the correct answer is (d) propanone.
