Vedclass · Answer

(C) $1$. The hydration of ethyne $(HC \equiv CH)$ in the presence of $1\% \ HgSO_4$ and $20\% \ H_2SO_4$ (Kuccherov reaction) yields acetaldehyde $(CH_3CHO)$ as product $A$.$2$. The reaction of acetaldehyde $(CH_3CHO)$ with a Grignard reagent $(CH_3MgX)$ followed by hydrolysis yields a secondary alcohol,propan$-2-$ol $(CH_3-CH(OH)-CH_3)$ as product $B$.$3$. The oxidation $([O])$ of propan$-2-$ol yields acetone $(CH_3-CO-CH_3)$.

$HC \equiv CH$ $\xrightarrow[20\% \ H_2SO_4]{1\% \ HgSO_4} A$ $\xrightarrow{CH_3MgX} B$ $\xrightarrow{[O]} ?$
