Q. The correct order of acid strength is :
A) HClO < HClO₂ < HClO₃ < HClO₄
B) HClO₄ < HClO < HClO₂ < HClO₃
C) HClO₂ < HClO₃ < HClO₄ < HClO
D) HClO₄ < HClO₃ < HClO₂ < HClO
Explanation
[Solution from source] Acid strength of chlorine oxoacids rises with the oxidation state of Cl (+1 to +7), as more oxygen atoms delocalise the negative charge of the conjugate base: HClO < HClO₂ < HClO₃ < HClO₄. HClO₄ is the strongest, not the weakest. Answer (1).
