Rank the following solutions in order of decreasing [H3O^+].

.10 M HC2H3C2
.10 M HC6H5O
.10 M HF
,10 M HBr

I think the correct order is: HBr>HF>HC2H3C2>HC6H5O

am i right?

Is that first one a typo and HC2H3O2 is correct? Is the second one phenol? Assuming both of those are true I think the order is correct.
The first one should read HC2H3O2. yes the second one is phenol
