### 9.25

I understand that when drawing the lewis structure of SO2F2 it results in 6 unique different combinations, however I'm a little confused when thinking of this molecule in a 3 dimensional space. I assume that since the question is stating that SO2F2 adopts a positionally disordered arrangement that position matters, however in a 3D space, what differentiates for example
F from F
O S F F S O
O O

I believe they are talking about if a bunch of SO2F2 molecules take a disordered arrangement as a whole. In a crystal structure, all the molecules are aligned perfectly so that they all look alike 3 dimensionally. This question asks if they are not all aligned the same way (like the fluorine atom on one is up while the oxygen atom on another is up). The structure of the molecule is tetrahedral by the way.
