Q. Which one of the following orders correctly represents the increasing acid strengths of the given acids?
A) HOClO < HOCl < HOClO₃ < HOClO₂
B) HOClO₂ < HOClO₃ < HOClO < HOCl
C) HOClO₃ < HOClO₂ < HOClO < HOCl
D) HOCl < HOClO < HOClO₂ < HOClO₃
Explanation
[Solution from source] Acid strength of chlorine oxoacids increases with the number of oxygen atoms, which raises chlorine's oxidation state and stabilises the conjugate base by delocalisation. So HOCl < HOClO < HOClO₂ < HOClO₃. Answer (4).
