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:

  1. Ethyne (acetylene) is passed through a hot tube. The heat provides the energy needed for the reaction to occur.

  2. 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.

  3. 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.
