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)C-=CH_(3)underset(Hg^(2+))overset(H^(+),H_(2)O)toCH_(3)CH_(2)underset(O)underset(||)(C)-CH_(3)`
