Question

convert propyne to propan-2-one

Answer 1

propyne reacts with water catalysed by HgSO4/H2SO4 to give propan-2-one

Answer 2

Propyne reacts with water catalyzed by $HgSO4/H2SO4$ to give propane-2-one following markownikoff's rule.

Explanation:

• Propyne reacts with water catalyzed by $HgSO4/H2SO4$ to give propane-2-one

• $H3C-C$≡$CH$ -------------- $H3C-C-CH3$
• Here addition reaction takes place in which markowinkoof's rule takes place.
• The reaction is carried out in the presence of sulphuric acid and mercuric acid.
• Thus propane when undergoing a water catalyzed reaction in the presence of catalyst gives propane 2 one.
