As the oxidation number of the central atom increases, strength of acid also increases. $\mathrm{HOCl}<\mathrm{HOClO}<{\mathrm{HOClO}}_2<{\mathrm{HOClO}}_3$ Related Theory The chlorine is more electronegative than bromine. As a result, it will attract electrons more towards itself than bromine. This will result in a donation of $\mathrm{H}+$ more easily in $\mathrm{HOCl}$ than in HOBr. So, the HOCl will be stronger acid than $\mathrm{HOBr}$.
