When acetylene is passed under pressure over an organo-nickel catalyst at 70°C _ is formed?
Correct answer: D. benzene
- A. Vinyl acetylene
- B. Di-vinyl acetylene
- C. Neoprene
- D. benzene
Explanation
When acetylene is passed under pressure over an organo-nickel catalyst at 70°C, it undergoes a trimerization reaction where three molecules of acetylene combine to form one molecule of benzene. The organo-nickel catalyst facilitates the cyclization process, allowing this transformation to occur.The other options are incorrect because they do not align with the trimerization reaction described in the question.

About Chemistry of Hydrocarbons
Hydrocarbons are studied through the structures and reactions of alkanes, alkenes, alkynes and aromatic compounds. Coverage includes free radical substitution in alkanes, electrophilic addition to carbon-carbon multiple bonds, benzene substitution, aromatic stability and the difference between addition reactions of alkenes and substitution reactions of benzene.
