Vedclass · Answer

(B) When a mixture of beryllium oxide $(X)$,carbon,and chlorine is heated at high temperature,beryllium dichloride $(Y)$ and carbon monoxide are obtained:$BeO + C + Cl_2 	o BeCl_2 + CO$The hydrolysis of beryllium dichloride $(Y)$ gives beryllium hydroxide $(Z)$ and $HCl$:$BeCl_2 + 2H_2O 	o Be(OH)_2 + 2HCl$Beryllium dichloride $(BeCl_2)$ is an electron-deficient molecule and exists in a polymeric chain structure in the solid state.

$X + C + Cl_2 \xrightarrow[> 1000 \ K]{\text{High temp.}} Y + CO$
$Y + 2H_2O \to Z + 2HCl$
Compound $Y$ is found in a polymeric chain structure and is an electron-deficient molecule. $Y$ must be:
