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

  • HOCl < HOClO < HOClO2 < HOClO3

  • HOClO < HOCl < HOClO3 < HOClO2

  • HOClO2 < HOClO3 < HOClO < HOCl

  • HOClO3 < HOClO2 < HOClO < HOCl

Solution

D.

HOClO3 < HOClO2 < HOClO < HOCl

The acidic character of oxyacids increases with increases in oxidation number. The acidity of oxyacids of chlorine decreases in the following order.
straight H Cl with plus 7 on top straight O subscript 4 space greater than thin space straight H Cl with plus 5 on top straight O subscript 3 space greater than thin space straight H Cl with plus 3 on top straight O subscript 2 space greater than thin space straight H Cl with plus 1 on top straight O
So relative acidic character increases.
