Question

benzene prepare with acetylene

Answer 1

By passing 3 moles of acetlyene in red hot iron tube in the presence of Chromic oxide or Ferric oxide
Benzene is prepared from ethyne by the process of cyclic polymerization. In this process, Ethyne is passed through a red hot iron tube at 873 K. The ethyne molecule then undergoes cyclic polymerization to form benzene.
