Chemistry Question on Acids and Bases

Of the given anions, the strongest base is

A

ClO− ClO^-

B

ClO2− ClO_2^-

C

ClO3− ClO_3^-

D

ClO4− ClO_4^-

Answer

ClO− ClO^-

Explanation

Solution

The order of acidic strength of conjugate acids is       HOCl<HCIO2<HCIO3<HClO4\, \, \, \, \, \, HOCl < HCIO_2 < HCIO_3 < HClO_4 Reverse is the order of basic strength of their conjugate base. i.e. CIO−CIO^- is the strongest base.
