How does acetylene react with:
(i) Water in the presence of dilute H₂SO₄and HgSO₄(ii) HCN in the presence of barium cyanide?

Solution

(i) The addition of water: Acetylene reacts with water in the presence of dilute sulphuric acid and mercuric sulphate to form an unstable product which undergoes rearrangement to give acetaldehyde.

(ii) The addition of hydrogen cyanide: Acetylene reacts with hydrogen cyanide in the presence of barium cyanide to form vinyl cyanide.
