In both acid the oxidation number of chlorine and bromine are same ,that is +3 . But chlorine atom is more electronegative than bromine atom . So the electron of O - H bond strongly attract Cl atom towards itself than bromine atom . ... Consequently , HClO2 is more stroger acid than HBrO2

HClO2 is a stronger acid than HBrO2 because Cl has a higher electronegativity than Br.

Usually the stronger acid is the element with the higher electronegativity.
