$Na / NH_3$ (liq.) and $Pd / BaSO_4 + H_2$

Vedclass · Answer

(A) The reduction of $2$-butyne with $Na / NH_3$ (liq.) (Birch reduction) yields the $E$-product (trans$-2-$butene) due to anti-addition of hydrogen.Conversely,the catalytic hydrogenation of $2$-butyne using Lindlar's catalyst $(Pd / BaSO_4 + H_2)$ yields the $Z$-product (cis$-2-$butene) due to syn-addition of hydrogen.Given the reaction scheme:$Z$-product $\stackrel{Y}{\longleftarrow} 2$-butyne $\stackrel{X}{\longrightarrow} E$-product$X$ must be $Na / NH_3$ (liq.) and $Y$ must be $Pd / BaSO_4 + H_2$.

What are $X$ and $Y$ respectively in the following reaction?
$Z$-product $\stackrel{Y}{\longleftarrow} 2$-butyne $\stackrel{X}{\longrightarrow} E$-product
