Vedclass · Answer

(A) Step $1$: $C_3H_6$ (Propene) reacts with $Br_2$ in $CCl_4$ to form $X$,which is $1,2$-dibromopropane $(CH_3-CHBr-CH_2Br)$.Step $2$: $1,2$-dibromopropane reacts with alcoholic $KOH$ followed by $NaNH_2$ and heat (dehydrohalogenation) to form $Y$,which is $CH_3-C \equiv CH$ (Propyne).Step $3$: Propyne undergoes hydration in the presence of $Hg^{2+}$ and $H^+$ at $333 \ K$ (Kucherov reaction) to form an enol intermediate,which tautomerizes to form $Z$,which is $CH_3-CO-CH_3$ (Acetone).

What is $Z$ in the following reaction sequence ?
$C_3H_6$ $\xrightarrow[CCl_4]{Br_2} \underset{\text{(colourless)}}{X}$ $\xrightarrow[\text{(ii) } NaNH_2, \Delta]{\text{(i) } KOH / \text{alcohol}} Y$ $\xrightarrow[\substack{Hg^{2+}, H^{+} \\ 333 \ K}]{H_2O} Z$
