When acetylene is passed under pressure over an organo-nickel catalyst at 70°C _ is formed?
Correct answer: D. Ethylene
- A. Vinyl acetylene
- B. Di-vinyl acetylene
- C. Neoprene
- D. Ethylene
Explanation
When acetylene (ethyne) is passed under pressure over an organo-nickel catalyst at 70°C, the product formed is ethylene (ethylene gas).The reaction can be represented as follows:C2H2 (acetylene) → C2H4 (ethylene).In this reaction, acetylene (C2H2) undergoes hydrogenation in the presence of the organo-nickel catalyst. Hydrogenation is the addition of hydrogen to the carbon-carbon triple bond of acetylene, converting it into ethylene (C2H4).Ethylene is a valuable industrial chemical and is used as a raw material in the production of various plastics and synthetic materials. The hydrogenation of acetylene to ethylene is an important reaction in the petrochemical industry.
