Addition of water to alkynes occurs in acidic medium and in the presence of `Hg^(2+)` ions as a catalyst. Which of the following products will be formed on addition of water to but-1-yne under these conditions ?

Options

A. `CH_(3)-CH_(2)-CH_(2)-overset(O)overset(|)C-H`
B. `CH_(3)-CH_(2)-overset(O)overset(||)C-CH_(3)`
C. `CH_(3)-CH_(2)-overset(O)overset(||)C-OH+CO_(2)`
D. `CH_(3)-overset(O)overset(||)C-OH+H-overset(O)overset(||)C-H`

Answer

B

Explanation

`CH_(3)CH_(2)CequivCHoverset(H^(+)//H_(2)O.Hg^(2+))tounderset("Butan-2-one ")(CH_(3)CH_(2)-overset(O)overset(||)C-CH_(3))`
