    Which one of the following pairs of molecules will have permanent dipole moments for both members?

    A) \[Si{{F}_{4}}\]and\[N{{O}_{2}}\]

    B)        \[N{{O}_{2}}\]and\[C{{O}_{2}}\]

    C) \[N{{O}_{2}}\]and\[{{O}_{3}}\]           

    D)        \[Si{{F}_{4}}\]and\[C{{O}_{2}}\]

    Correct Answer: C

    Solution :

    [c] \[Si{{F}_{4}}\] and \[C{{O}_{2}}\] have zero dipole moment due to symmetrical tetrahedral and linear structures, \[N{{O}_{2}}\] and \[{{O}_{3}}\] both have V-shape and certain value for dipole moment.
