Vedclass · Answer

(A) The synthesis of $1, 3-$butadiene from acetylene $(C_2H_2)$ involves two main steps: $1$. Dimerization of acetylene: Acetylene undergoes linear dimerization in the presence of $CuCl$ and $NH_4Cl$ to form vinylacetylene $(CH_2=CH-C \equiv CH)$. $2$. Partial hydrogenation: Vinylacetylene is then selectively hydrogenated using $H_2/Pd(BaSO_4)$ (Lindlar's catalyst) to reduce the triple bond to a double bond,yielding $1, 3-$butadiene $(CH_2=CH-CH=CH_2)$.

Which of the following order of reagents is chosen to prepare $1, 3-$butadiene from $C_2H_2$?
