Question
Ethyne is passed through a hot tube containing organo-nickel catalyst to produce:
- A. isoprene
- B. polythene
- C. ethanol
- D. benzene
Solution
The reaction you're referring to is the process of passing ethyne (acetylene) through a hot tube containing an organo-nickel catalyst. This process is known as the Reppe synthesis, named after Walter Reppe, a German chemist.
Here are the steps:
-
Ethyne (acetylene) is passed through a hot tube. The heat provides the energy needed for the reaction to occur.
-
The tube contains an organo-nickel catalyst. A catalyst is a substance that speeds up a chemical reaction without being consumed in the reaction itself. In this case, the organo-nickel catalyst facilitates the polymerization of the ethyne.
-
The ethyne reacts in the presence of the organo-nickel catalyst, leading to the formation of a new compound.
The product of this reaction is benzene. So, the correct answer is D. Benzene.
