    A) \[P{{Q}_{2}}\,,\,\,6\,\,:\,\,6\]

    B) PQ, 6 : 6

    C) \[{{P}_{2}}Q,\,\,6\,\,:\,\,8~\]

    D) PQ, 8 : 8

    Correct Answer: D

    Solution :

    No. of atoms of \[P=8\times \frac{1}{8}=1\] No. of atoms of  \[Q=1\times 1=1\] The formula of the compound is PQ. Coordination no. of P and Q = 8 : 8
