oxoacids

[Michael Du 1E]

In today's lecture, for the last past exam question that we went over, can anyone please explain again why the H was bonded to the O atom instead of the Cl atom? (molecule is HClO3) Thank you!

That is simply the common structure of all oxoacids. (H3PO4, H2SO4, HNO3, etc.) If the H was bonded to the Cl atom, I assume it that would make the conjugate base much less stable and that's why we don't see that happen in nature.

Oxoacids have an O-H hydrogen bond which dissociates into H+ ions in solution and this is how it acts as an acid. If the H were bonded to the Cl in the example in class this wouldn't happen.

Oxoacids are a category of acids that contain oxygen(s) which hold/bond to the soon-to-be-donated hydrogen/proton. HClO3 falls into the oxoacids category.
