Question

Though b-f bond is polar in nature yet bf3 molecule has no dipole moment ? why.

Answer 1

Explanation:

because B and F has Electronegativity defference greater than zero but less than 2 so it is the reason for their polarity and has no dipole movement because we take it as net concurrent forces and when look upon it , it doesn't give us any resultant force so that's why it's dipole movement is 0
