    B)        \[\operatorname{MgO} and N{{a}_{2}}O\]

    C) \[{{\operatorname{Na}}_{2}}O\,\,and\,\,BaO\]   

    D) \[\operatorname{SnC}{{l}_{2}}\,\,and\,\,SnC{{l}_{4}}\]

    Correct Answer: D

    Solution :

    \[SnC{{l}_{2}}\]                       \[SnC{{l}_{4}}\] \[119:2\times 35.5\]                     \[119:4\times 35.5\] Chlorine ratio in both compounds is \[=\,\,2\times 35.5 :4\times 35.5=1:2\]
