Vedclass · Answer

(A) The reaction sequence is as follows:$1$. Heating coke $(C)$ with lime $(CaO)$ gives calcium carbide $(CaC_2)$,which is compound $X$.$CaO + 3C \xrightarrow{\Delta} CaC_2 + CO$$2$. Calcium carbide reacts with water to form acetylene $(C_2H_2)$,which is compound $Y$.$CaC_2 + 2H_2O ightarrow C_2H_2 + Ca(OH)_2$$3$. Passing acetylene over red-hot iron at $873 \ K$ leads to cyclic trimerization to produce benzene $(C_6H_6)$,which is compound $Z$.$3C_2H_2 \xrightarrow{	ext{Fe, } 873 \ K} C_6H_6$ (Benzene)Thus,the correct option is $A$.

$A$ compound $X$ formed after heating coke with lime reacts with water to give $Y$,which on passing over red-hot iron at $873 \ K$ produces $Z$. The compound $Z$ is
