Benzene can be obtained from trimerization of-
1 Hexane
2 Ethyne
3 Cyclohexane
4 Cyclopropane
Explanation:
When ethyne is passed through a red hot tube at \(500^{\circ}-600^{\circ} \mathrm{C}\) it trimerises to form benzene \(\mathop {{\text{3H - C}} \equiv {\text{C}}}\limits_{{\text{ethyne}}} {\text{ - H}}\xrightarrow{{{\text{500 - 600}}^\circ {\text{C}}}}\mathop {{{\text{C}}_{\text{6}}}{{\text{H}}_{\text{6}}}}\limits_{{\text{benzene}}} \) Benzene is an aromatic hydrocarbon which possess a characteristic pleasant smell.
