The set with correct order of acidity is

Show answer and solution
According to conjugate acid-base theory, that acid is more
acidic whose conjugate base is more stable. The order of the stability

of the conjugate bases of these acids is as follows:

ClO- < ClO2- < ClO3- < ClO4- on the basis of the charge

dispersion on the oxygen atoms (more charge dispersion on oxygen

atoms, more stable is the conjugate base). Also, for oxyacids of same

element, as oxidation state of element increases, acidic strength of

oxyacids increases.
