Among the following, the correct order of acidity is:

A $HClO < HClO_{2} < HClO_{3} < HClO_{4}$
B $HClO_{2} < HClO < HClO_{3} < HClO_{4}$
C $HClO_{4} < HClO_{2} < HClO < HClO_{3}$
D $HClO_{3} < HClO_{4} < HClO_{2} < HClO$

Solution & Step-by-step Explanation

For oxoacids of the same element, acidity increases with the increase in the oxidation state of the central atom. HClO (+ 1), HClO_{2} (+ 3), HClO_{3} (+ 5), HClO_{4} (+ 7) .Alternatively, higher the number of oxygen atoms, more stable the conjugate base due to resonance.
