Q50.Among the following oxoacids, the correct decreasing order of acid strength is : (1) HOCl > HClO2 > HClO3 > HClO4 (2) HClO4 > HOCl > HClO2 > HClO3 (3) HClO4 > HClO3 > HClO2 > HOCl (4) HClO2 > HClO4 > HClO3 > HOCl
What This Question Tests
This question directly tests the rule for determining the relative acid strength of oxoacids of the same element, which increases with the increasing oxidation state of the central atom.
