Net Dipole Moment
Does BrF6 have a net dipole moment? I know that F is more electronegative, so the dipole moment travels from the central Br to each F atom. When I draw all of these vectors out, I think they sum up to be 0. Is this correct? Is there another way to look at this?

Re: Net Dipole Moment
The net dipole moment is 0 since the dipoles cancel out in an octahedral shape.
Re: Net Dipole Moment
Yes, since as mentioned above, in an octahedral shape, it is most stable and net dipole moments is 0.

Re: Net Dipole Moment
The dipole moments cancel each other out since they are all, essentially, the same (the only bond is a Br-F bond). If they were not all the same element (not all F or any other atom), then the dipole moments would not cancel, resulting in a net dipole moment.

One way to see that the net dipole moment is 0 is to draw out the VSEPR structure. Then, draw electronegativity arrows from the Br atom to each F atom. Using this, you'll be able to see how each electronegativity arrow cancels out with another. Thus, you can confirm that the net dipole moment is 0.
