    The correct order of dipole moment is:

    A)  \[C{{H}_{4}}<N{{F}_{3}}<N{{H}_{3}}<{{H}_{2}}O\]

    B)     \[N{{F}_{3}}<C{{H}_{4}}<N{{H}_{3}}<{{H}_{2}}O\]

    C)     \[N{{H}_{3}}<N{{F}_{3}}<C{{H}_{4}}<{{H}_{2}}O\]

    D)     \[{{H}_{2}}O<N{{H}_{3}}<N{{F}_{3}}<C{{H}_{4}}\]

    Correct Answer: A

    Solution :

    In\[{{H}_{2}}O,\]electronegativity difference is highest. So, dipole moment is highest in this. \[C{{H}_{4}}\] is a symmetrical tetrahedral structure and its dipole moment is zero.
