The correct sequence of reagents for the following conversion will be

Options

A ${O}_{3} / RedP, {AlCl}_{3}, MeCOOH$
B ${H}_{2}{SO}_{4} + {HgSO}_{4}, {H}_{2}O / Heat$
C ${O}_{3} / Zn - AcOH, {H}_{2}{SO}_{4} + {HgSO}_{4} / {H}_{2}O / Heat$
D ${CH}_{3}COOH, {H}_{2}{O}_{2} + OH / {H}_{2}O$

Correct answer

B. ${H}_{2}{SO}_{4} + {HgSO}_{4}, {H}_{2}O / Heat$

Step-by-step solution

$R - C ≡ CH$ is converted to ketone by catalytic hydration with reagents.

Hydration of alkynes is carried out in the presence of a warm 40% sulfuric acid in the presence of 1% mercuric sulfate.

In this reaction, first a molecule of water is added to form enol which then tautomerizes to keto form.&
