    Directions : In the following question more than one of the answers given may be correct. Select the correct answer and mark it according to the code:

    Carbon dioxide is isostructural with (1)\[HgC{{l}_{2}}\]                                           (2)\[SnC{{l}_{2}}\] (3)\[{{C}_{2}}{{H}_{2}}\]                               (4)\[N{{O}_{2}}\]

    A)  1, 2 and 3 are correct

    B)  1 and 2 are correct

    C)  2 and 4 are correct

    D)  1 and 3 are correct

    Correct Answer: D

    Solution :

                     The structure of carbon dioxide is linear as \[O=C=O\] \[\underset{(HgC{{l}_{2}})}{\mathop{Cl-Hg-Cl;}}\,\]        \[\underset{({{C}_{2}}{{H}_{2}})}{\mathop{H-C\equiv C-H}}\,\] \[SnC{{l}_{2}}\]and\[N{{O}_{2}}\]have angular structure.
