Vedclass · Answer

(C) The acidic strength of oxoacids is directly proportional to the electronegativity of the central atom when the oxidation state is the same. For the series $HClO_4$,$HBrO_4$,and $HIO_4$,the central atoms are $Cl$,$Br$,and $I$ respectively. Since electronegativity decreases down the group $(Cl > Br > I)$,the acidic strength follows the order $HClO_4 > HBrO_4 > HIO_4$.

Which of the following represents the correct order of acidic nature?
