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

But-10yne one reaction with water in presence of `Hg^(2+)` ions as a catalyst produces butan-2-one.
