Acetaldehyde is prepared b-ty he reaction of ethyne with water in the presence of HgSO4/H2SO4 at 75°C. Number of steps involved in this reaction are:
Correct answer: C. 2
- A. 1
- B. 4
- C. 2
- D. 3
Explanation
The preparation of acetaldehyde from ethyne (acetylene) and water in the presence of HgSO4/H2SO4 at 75°C involves two steps.The overall reaction can be represented as follows:Step 1: Addition of water to ethyne (hydration)C2H2 + H2O → CH3CHO (acetaldehyde).In this step, ethyne undergoes hydration, where water adds across the triple bond to form acetaldehyde.Step 2: Formation of acetaldehyde.CH3CHO (acetaldehyde).In this step, the acetaldehyde formed in Step 1 is the final product of the reaction.So, the preparation of acetaldehyde from ethyne involves two steps.
