Addition of water to alkyness occurs in acidic medium and in the presence of `Hg^(2+)` ions as a catalyst. Which of the following products will be formed on additon 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

`underset("But-1-yne")underset()(CH_(3)-CH_(2)-C)equivCH+H_(2)Ooverset(H_(2)O)underset((Hg^(2+)//H^(+)))rarrunderset("Butanone")underset()(CH_(3)-CH_(2)-overset(O)overset(||)C-CH_(3))`
