With the help of Cyclic polymerization, Benzene can be prepared from
Correct answer: C. Alkyne
- A. Alkane
- B. Alkene
- C. Alkyne
- D. Alkyl
Explanation
Benzene can be prepared from alkynes through a process called cyclic polymerization. In cyclic polymerization, three alkyne molecules are joined together to form a benzene molecule. The reaction is shown below:3C2H2 ? C6H6Alkanes do not have double bonds required for polymerization. Alkenes can only form linear molecules, not cyclic like benzene. Alkyl is not a molecule and cannot be polymerized.

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.
