Question

why BF3 has a zero dipole moment although the BF bonds are polar ​

Answer 1

Answer:

Boron trifluoride is has zero dipole moment although it has three polar B—F bonds. This is because BF3 has sp2 hybridisation and regular trigonal planal geometry. And hence the individual dipole moments of polar bonds get cancelled and overall dipole moment is zero.

Explanation:

Answer 2

HELLO!!

BF₃ has zero dipole moment even thow B - F bonds are polar. BF₃ has a Trigonal planar geometry, with the speciality of backbonding. The individual dipole moments cancel each other, so the net dipole moment is zero. Refer to the attachment.
