1.	Fluorine is more electronegative than either boron or phosphorus. Whatconclusion can be drawn from the fact that BF_(3) has no dipole moment nut PF_(3) does ?
Answer» `BF_(3)` is not spherically SYMMETRICAL but `PF_(3)` is `BF_(3)` MOLECULE must be linear The atomic radius of P is larger than that of B The `BF_(3)` molecule must be planar triangular Solution :The B-F bond is polar, YET `BF_(3)` is non-polar because `BF_(3)` has a planar triangular STRUCTURE.
