Question

An oxide of alkaline earth metals (X) reacts with C and $Cl_{2}$to give a compound Y. Y is found in polymeric chain structure and is electron deficient molecule. The compound Y is.

• A. BeO
• B. $BeCl_{2}$
• C. $Be(OH)_{2}$
• D. $BeCO_{3}$

Answer 1

Answer: (B)

$BeCl_{2}$

: $\underset{(X)}{BeO} + C + Cl_{2} \rightarrow \underset{(Y)}{BeCl_{2}} + CO$

$BeCl_{2}$ is polymeric and electron deficient molecule.
