Question

How is the above transformation best carried out?

• A. $Os{O}_4:NaHS{O}_3$
• B. $H_{2}S{O}_4/H_{2}O$
• C. $HgS{O}_4/H_{2}S{O}_4$
• D. $HI{O}_4$

Answer 1

The correct option is C $HgS{O}_4/H_{2}S{O}_4$

$\begin{array}{c}{\text{On addition of HgSO}}_4/{\text{H}}_2{\text{SO}}_4\text{with alkyne adds OH to most}\text{hindered carbon and H to least hindered Carbon i.e}\\ \text{addition of water.}\end{array}$
