JEE Main & Advanced Chemistry Chemical Bonding and Molecular Structure Question Bank Dipole moment

  • question_answer Fluorine is more electronegative than either boron or phosphorus. What conclusion can be drawn from the fact that \[B{{F}_{3}}\] has no dipole moment but \[P{{F}_{3}}\] does [Pb. PMT 1998]

    A)                 \[B{{F}_{3}}\]is not spherically symmetrical but \[P{{F}_{3}}\] is

    B)                 \[B{{F}_{3}}\]molecule must be linear

    C)                 The atomic radius of \[P\] is larger than the atomic radius of \[B\]

    D)                 The \[B{{F}_{3}}\] molecule must be planar triangular

    Correct Answer: D
