Question

When acetylene (C2H2) gas is passed through red hot iron tube, it trimerises into benzene (C6H6) vapours. If the average molar mass of vapours coming out through the tube is 50, calculate the degree of trimerisation of acetylene. Please explain.​

Answer 1

Answer:

cetylene on passing through red hot iron tube at 873K undergoes cyclic polymerization.

Three of the acetylene molecules polymerise to form benzene.

This is the best route for entering from aliphatic to aromatic compounds.

Explanation:

It is benzene. This is the famous Deils Alder reaction. When Acetylene(C2H2) is passed through red hot iron tube, it trimerises to give you Benzene (C6H6)
