    In which of the following, the dipole moment is zero?

    A) \[{{H}_{2}}{{O}_{2}}\]                   

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

    C)  \[S{{O}_{2}}\]                                  

    D)  \[N{{H}_{3}}\]

    Correct Answer: B

    Solution :

    Key Idea: The dipote moment of molecules having regular geometry or linear structure is zero. Dipole moment is vector quantity. [a] \[{{H}_{2}}{{O}_{2}}-\]open book structure [b] \[C{{O}_{2}}-\]linear structure \[O=C=O\] [c] \[S{{O}_{2}}-\]bent structure [d] \[N{{H}_{3}}-\]pyramidal structure
