We’re being asked to rank the given compounds from the strongest acid on the left to weakest acid on the right.
All of the given compounds possess an H+ ion connected to a nonmetal and oxygen (or H+ + negative polyatomic ions + oxygen/s), therefore they are all oxyacids. We can compare their strengths using the following guides:
The strength of oxyacids is based on the number of oxygens or the electronegativity of the nonmetal in the oxyacid. An oxyacid is considered strong when there are at least 2 or more O than H.
Rank the following from strongest acid on the left to weakest acid on the right.
A. HOBr > HOBrO > HOBrO2 > HOBrO3
B. HOBrO2 > HOBrO > HOBr > HOBrO3
C. HOBrO > HOBrO3 > HOBrO2 > HOBr
D. HOBrO3 > HOBrO2 > HOBrO > HOBr
E. none of the above
