Among the following, the correct order of acidity is

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

Solution

The increasing order of acidity is $$\displaystyle HClO < HClO_{2} < HClO_{3} < HClO_{4}$$
+1 +3 +5 +7
