Question

Which of the following order of acid strengths are correct ?

• A. HOI <HOBr<HOCl
• B. HCl<HBr< HI
• C. HIO₄< HBrO₄< HClO₄
• D. All of the above are correct order

Answer 1

Answer: (D)

All of the above are correct order

Answer 2

In HOX with increase in electronegativity acid strength increases

In H – X acid strength increases with decrease in bond energies.

In HXO₄ acid strength increases with decrease in size of X.
