Single Choice

The correct order of acid strength is.

A$$HClO < HClO_2 < HClO_3 < HClO_4$$
Correct Answer
B$$HClO_4 < HClO < HClO_2 < HClO_3$$
C$$HClO_2 < HClO_3 < HClO_4 < HClO$$
D$$HClO_4 < HClO_3 < HClO_2 < HClO$$

Solution

Correct order of acid strength is:

$$\underset {+1}{HClO} <\underset {+3}{HClO_2} <\underset {+5}{HClO_3}< \underset {+7}{HClO_4} $$

($$\because$$ acid strength $$\propto$$ oxidation number)

Hence, option $$A$$ is correct.
