Question

define the dipole moment BF3​

Answer 1

Explanation:

The BF3

molecule has a symmetrical trigonal planar geometry, like the SO3

molecule.

In such a structure, the resultant moment of any two B−F dipoles is equal in magnitude but opposite in direction to the moment of the third one.

So, the net dipole moment of the BF3

molecule is zero, and it is non-polar
