Question

How to convert ethyne to benzene?

Answer 1

Conversion of Ethyne to Benzene:-

Step 1: Formation of Benzene

• When Ethyne is passed through a red hot iron tube at a temperature of $873\mathrm{K}$ it produces Benzene.
• One bond from each of the ethyne breaks and connects to the adjacent Ethyne molecule to form a ring-like structure, that is Benzene.

This conversion of Ethyne to Benzene is a 1 step reaction.

Therefore, Ethyne when passed through red hot Iron tube at $873\mathrm{K}$, Benzene is produced.
