Question

Explain with chemical equation. What happens when :
1. Passing acetylene gas in solution of ammonical cuprous chloride?
2. Passing acetylene gas in red hot tube?
3. Acetylene is passed in dilute sulphuric acid?
4. Acetylene is passed in hydrochloric acid in the presence of mercuric sulphate?
5. Acetylene is passed in aqueous solution containing Hg⁺⁺ and H⁺ ions?
6. Acetylene gas is passed in hypochlorous acid?

Answer 1

(1) On passing acetylene gas in solution of ammonical cuprous chloride, acetylene undergoes linear polymerization.

(2) On passing acetylene gas in red hot tube, it polymerizes to benzene.

(3) When acetylene is passed in dilute sulphuric acid, it forms ethylidene hydrogen sulphate.

(4) When acetylene is passed on hydrochloric acid in the presence of mercuric sulphate, it gives vinyl chloride.

(5) When acetylene is passed in aqueous solution containing Hg⁺⁺ and H ⁺ ions, it gives acetaldehyde.

(6) When acetylene is passed in hypochlorous acid, it gives 1, 1-dichloro acetaldehyde.
