Vedclass · Answer

(A) From the given reactions:$1$. $X + HCl \rightarrow C_2H_5Cl$ (Addition reaction indicates $X$ is an alkene,$C_2H_4$).$2$. $Y + HCl \rightarrow C_2H_5Cl$ (Substitution reaction indicates $Y$ is an alcohol,$C_2H_5OH$).$3$. The conversion of $Y$ $(C_2H_5OH)$ to $X$ $(C_2H_4)$ is a dehydration reaction.$4$. Dehydration of ethanol to ethene occurs by heating with $Al_2O_3$ at $350^{\circ}C$.$\underset{(Y)}{C_2H_5OH} \xrightarrow[350^{\circ}C]{Al_2O_3} \underset{(X)}{C_2H_4} + H_2O$

Consider the following reactions:
$X + HCl \xrightarrow{\text{Anhydrous } AlCl_3} C_2H_5Cl$ (Addition)
$Y \xrightarrow{\text{Anhydrous } ZnCl_2 / HCl} C_2H_5Cl$ (Substitution)
$Y$ can be converted to $X$ on heating with $...$ at $...$ temperature:
