### 2C.3

For part C of this question, I'm a little confused as to how there is resonance with the structure for HClO3. The structure you end up with (with the lowest formal charge) doesn't have any bonds that can be switched without changing the number of double/single bonds in the molecule, yet the answer key provides three structures with different formal charges on the elements in each molecule. Can someone explain how this is possible and if we will be tested on this?

I've attached a picture of the answer from the answer key to help explain my confusion a little more. Thanks!
