Vedclass · Answer

(C) The strength of oxyacids of halogens increases with the increase in the oxidation state of the central halogen atom.In $HOCl$,the oxidation state of $Cl$ is $+1$.In $HOClO$,the oxidation state of $Cl$ is $+3$.In $HOClO_2$,the oxidation state of $Cl$ is $+5$.In $HOClO_3$,the oxidation state of $Cl$ is $+7$.Since $HOClO_3$ has the highest oxidation state $(+7)$,it is the strongest acid.
