    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 dipole 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 \[O=C=O\] \[\therefore \]Dipole moment is zero [c] \[\text{S}{{\text{O}}_{\text{2}}}-\]bent structure [d]\[\text{N}{{\text{H}}_{\text{3}}}-\]pyramidal structure
