    With which of the given pairs\[C{{O}_{2}}\]resembles in structure?

    A)  \[HgC{{l}_{2}},{{C}_{2}}{{H}_{2}}\]

    B)  \[HgC{{l}_{2}},SnC{{l}_{2}}\]

    C)  \[{{C}_{2}}{{H}_{2}},N{{O}_{2}}\]

    D)  \[{{N}_{2}}O\]and\[N{{O}_{2}}\]

    Correct Answer: A

    Solution :

                     \[C{{O}_{2}}\]is linear in structure. \[HgC{{l}_{2}}\]and\[HC\equiv CH({{C}_{2}}{{H}_{2}})\]both are linear in structure. \[HgC{{l}_{2}}\]is linear but\[SnC{{l}_{2}}\]is tetrahedral in structure. \[{{C}_{2}}{{H}_{2}}\]is linear but\[N{{O}_{2}}\]is bent  \[{{N}_{2}}O\]is linear but\[N{{O}_{2}}\] is bent in structure.
