Consider the following reactions

$Y$ can not be obtained from which of the following reaction?
$\mathrm{CH}_3 \mathrm{COCl}+\mathrm{H}_2 \xrightarrow[\mathrm{BaSO}_4]{\mathrm{Pd} /}$
$\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{OH} \xrightarrow{\mathrm{Cu} / 573 \mathrm{~K}}$
$\mathrm{CH}_3 \mathrm{CN}+\mathrm{SnCl}_2+\mathrm{HCl} \longrightarrow X \xrightarrow{\mathrm{H}_3 \mathrm{O}^{+}}$
$\mathrm{CH}_3 \mathrm{COOH} \xrightarrow[\text { (i) } \mathrm{H} / \mathrm{H}_2 \mathrm{O}]{\text { O } \mathrm{LiAl}_2}$
Assertion (A) : Carboxylic acids are more acidic than phenols
Reason (R) : Resonance structures of carboxylate ion are equivalent, while resonance structures of phenoxide ion are not equivalent.
In the reaction sequence $Y$ is
$$ \mathrm{CH}_3 \mathrm{CO}_2 \mathrm{H} \xrightarrow[(2) \Delta]{(1) \mathrm{NH}_3} P \xrightarrow{\mathrm{Br} / \mathrm{NaOH}} Y $$
