Which one of the following is the product (Z) formed at the end of the given reaction:
\[
\text{Propan-1-ol} + SOCl_2 \rightarrow [X]
\]
\[
[X] + HC \equiv C^-Na^+ \rightarrow [Y]
\]
\[
[Y] + H_2SO_4/HgSO_4,\; 330K \rightarrow [Z]
\]
Show Hint
Terminal alkynes on hydration with \( H_2SO_4/HgSO_4 \) give methyl ketones after enol-keto tautomerism.
