    The correct order of dipole moment is

    A)  \[B{{F}_{3}}<{{H}_{2}}S<{{H}_{2}}O\]

    B) \[{{H}_{2}}S<B{{F}_{3}}<{{H}_{2}}O\]

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

    D) \[{{H}_{2}}O<B{{F}_{3}}<{{H}_{2}}S\]

    Correct Answer: A

    Solution :

    Oxygen is more electronegative than sulphur. Hence, the order of dipole moment is as \[B{{F}_{3}}<{{H}_{2}}S<{{H}_{2}}O\]
