Question

CH3-C ≡ch in presence of hgso4 and h2so4​

Answer 1

Answer:

Explanation:Hydration of alkynes is carried out in the presence of a warm 40% sulfuric acid in the presence of 1% mercuric sulfate.

In this reaction, first a molecule of water is added to form enol which then tautomerizes to keto form.

Answer 2

Answer:

CH₃-C≡CH in the presence of HgSO₄ and H₂SO₄ forms acetone.

Explanation:

In the presence of hot dilute H₂SO₄ and HgSO₄, alkynes add a molecule of water. Carbonyl compounds are the product of this reaction. This addition of water occurs in the presence of mercuric sulphate and dilute sulphuric acid at 333 K.

The reaction is shown below.

                                Hg²⁺/H⁺

CH₃-C≡CH + H₂O  -------------→  [CH₃-CH(OH)=CH₂] --------→ CH₃-CO-CH₃

Propyne in the presence of HgSO₄ and H₂SO₄ adds a molecule of water to form prop-1-en-2-ol, which is unstable. This undergoes tautomerisation to form acetone.
