An oxide of alkaline earth metals $$X$$ reacts with $$C$$ and $$C{l_2}$$ to give a compound $$Y.$$ $$Y$$ is found in polymeric chain structure and is electron deficient molecule. The compound $$Y$$ is
A.
$$BeO$$
B.
$$BeC{l_2}$$
C.
$$Be{\left( {OH} \right)_2}$$
D.
$$BeC{O_3}$$
Answer :
$$BeC{l_2}$$
Solution :
$$\mathop {BeO}\limits_{\left( X \right)} + C + C{l_2} \to \mathop {BeC{l_2}}\limits_{\left( Y \right)} + CO$$
$$BeC{l_2}$$ is polymeric and electron deficient molecule.
