Predict the product of acid hydrolysis of CH3 -C≡C- CH3 in the presence of HgSO4 catalyst.
Correct answer: D. Butanone
- A. Acetaldehyde
- B. Propanal
- C. 2-Butanol
- D. Butanone
Explanation
The acid hydrolysis of an alkyne, such as CH3-C≡C-CH3, in the presence of a mercury(II) sulfate (HgSO4) catalyst proceeds through a process known as hydration. In this reaction, water adds across the triple bond of the alkyne to form a ketone. The ketone formed is butanone.

About Alkynes
Alkynes are unsaturated hydrocarbons containing a carbon-carbon triple bond, with sp-hybridised carbon atoms and a linear arrangement around the bond. The content includes nomenclature, preparation, acidity of terminal alkynes, and addition reactions with hydrogen, halogens, hydrogen halides and water, as well as oxidation.
