    The molecule which has zero dipole moment is

    A)  \[C{{H}_{3}}Cl\]

    B)  \[N{{F}_{3}}\]

    C)  \[B{{F}_{3}}\]

    D)  \[Cl{{O}_{2}}\]

    Correct Answer: C

    Solution :

     The molecules having distorted geometry have dipole moment and those having regular geometry have zero dipole moment. \[\because \] \[N{{H}_{3}},C{{H}_{3}}Cl\]and \[Cl{{O}_{2}}\]have distorted geometry. \[\therefore \]They have dipole moment. \[\because \]\[\text{B}{{\text{F}}_{\text{3}}}\] has regular triangular planar geometry. The dipole moment of \[\text{B}{{\text{F}}_{\text{3}}}\]is zero.
