### Calculating W

For BF3, would the degeneracy be at 1, because we can't tell if it would rotate, where as for BF2Cl it would be much higher as we could tell if it rotates with the Cl?

### Re: Calculating W

Yes, you are correct that the degeneracy of BF3 would be 1 as you can't distinguish between the positions the F atoms occupy. For BF2Cl the degeneracy value would be 3 as the Cl could occupy any of the three bonds in the triangular planar shape.
