Which one of the following orders correctly represents the increasing acid strengths of the given acids?

1. HOClO < HOCl < HOClO2 < HOClO3
2. HOClO2 < HOClO3 < HOClO < HOCl
3. HOClO3 < HOClO2 < HOClO < HOCl
4. HOCl < HOClO < HOClO2 < HOClO3

Correct answer: HOCl < HOClO < HOClO2 < HOClO3

Solution

The acid strength of oxoacids of chlorine increases with the number of oxygen atoms attached to the central chlorine atom due to increased electronegativity and inductive effects. Thus, the correct order is HOCl < HOClO < HOClO2 < HOClO3.
