Acetylene polymerizes to give:
Acetylene polymerizes to give:
- A. benzene
- B. polyethene
- C. butane
- D. octane
Step-by-step solution
Acetylene (C2H2) undergoes cyclic trimerization when heated or passed through a red-hot tube, forming benzene (C6H6). This is a characteristic reaction of alkynes. The other options (polyethene, butane, octane) are not products of acetylene polymerization under typical conditions.
