Question

Bond between Boron and Fluorine i.e. B - F bond is polar whereas BF is a neutral molecule . Explain how​

Answer 1

Explanation:

Though the B−F bond in BF3

Is polar, but they arrange themselves in trigonal planar geometry and hence cancel out each other due to symmetry.Therefore, there is no net dipole moment.

Answer 2

Answer:

Boron trifluoride (BF3) is a nonpolar molecule, whereas ammonia (NH3) is a polar molecule. The difference in polarities is related to the fact that :
