Vedclass · Answer

(D) The given reaction is the Reppe carbonylation of acetylene: $CH \equiv CH + CO + H_2O \xrightarrow{Ni(CO)_4} CH_2 = CH - COOH$. The product formed is acrylic acid $(CH_2 = CH - COOH)$. Statement $A$ is true: Acrylic acid is an $\alpha, \beta$-unsaturated acid. Statement $B$ is true: The reaction involves the addition of $H$ and $COOH$ across the triple bond. Statement $C$ is true: The product is indeed acrylic acid. Statement $D$ is false: Acrylic acid $(CH_2 = CH - COOH)$ reacts with ethyl alcohol $(C_2H_5OH)$ to form ethyl acrylate $(CH_2 = CH - COOC_2H_5)$,not ethyl butanoate.

$CH \equiv CH + CO + H_2O \xrightarrow{Ni(CO)_4} \text{Product}$. For this reaction,which statement is false?
