Fluorine is more electronegative than either boron or phosphorus. What conclusion can be drawn from the fact that has no dipole moment but
does
is not spherically symmetrical but
is
molecule must be linear
The atomic radius of P is larger than the atomic radius of B
The molecule must be planar triangular
molecule is Trigonal planar and as a result, the three polar BF bonds are arranged at an angle of
which leads to a net zero dipole.
Hence, the correct answer is Option (4)
