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.

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.
