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

But-1-yne on reaction with water in presence of `Hg^(2+)` ions as a catalyst produces butan-2-one
