Question
Arrange the following oxyacids of chlorine in decreasing order of their thermal stability. Give reason.
HOClO, HOCl, HClO4, HOClO2
Solution
Decreasing order of thermal stability of oxoacids of chlorine:
HCIO4 > HCIO3 > HCIO2 > HClO
Reason: With the decrease in the oxidation state of chlorine, the oxidizing power of its oxoacids increases and the thermal stability of oxoacids of chlorine decreases.
