When ethyne is passed through a red hot tube, _ is formed

Correct answer: B. Benzene

  • A. Cyclohexane
  • B. Benzene
  • C. Neoprene
  • D. Ethane

Explanation

When ethyne is passed through a red hot tube, it undergoes cyclic polymerization to form benzene. This process involves the combination of 3 ethyne molecules to produce benzene. The other options, such as cyclohexane, neoprene, and ethane, are incorrect because they do not result from the polymerization of alkynes in a red hot tube.
