Vedclass · Answer

(A) The reaction of calcium carbide with water produces acetylene $(C_2H_2)$:$CaC_2 + 2H_2O 	o C_2H_2 + Ca(OH)_2$Acetylene undergoes hydration in the presence of $dil. H_2SO_4$ and $HgSO_4$ (Kucherov reaction) to form an unstable enol intermediate,which tautomerizes to acetaldehyde $(CH_3CHO)$:$C_2H_2 + H_2O \xrightarrow{H_2SO_4/HgSO_4} [CH_2=CHOH] 	o CH_3CHO$Therefore,$A = C_2H_2$ and $B = CH_3CHO$.

$CaC_2 + H_2O \to A \xrightarrow{H_2SO_4/HgSO_4} B$. Identify $A$ and $B$ in the given reaction.
