    Which of the following will have maximum dipole moment?

    A)  \[N{{F}_{3}}\]

    B) \[N{{H}_{3}}\]

    C) \[C{{H}_{4}}\]

    D)  \[PC{{l}_{3}}\]

    Correct Answer: B

    Solution :

     \[\text{N}{{\text{H}}_{\text{3}}}\]has the maximum dipole moment, i.e., 1.46 D. This is because. in case of \[\text{N}{{\text{H}}_{\text{3}}}\]the orbital dipole due to lone pairs is in the same direction as the resultant dipole moment of N?H bonds.
