Vedclass · Answer

(B) $pK_a$ value of an acid is inversely proportional to its acidic strength,i.e.,the stronger the acid,the lower its $pK_a$ value.Acidic strength increases with an increase in the oxidation number of the central chlorine atom.The oxidation numbers of the central atom in the given acids are:AcidOxidation Number of $Cl$$HClO$$+1$$HClO_2$$+3$$HClO_3$$+5$$HClO_4$$+7$The acidic strength follows the order: $HClO Therefore,the $pK_a$ order is the inverse of the acidic strength order: $HClO_4 < HClO_3 < HClO_2 < HClO$.

The $pK_a$ of oxoacids of chlorine in water follows the order
