Bromic acid When comparing HClO, HBrO, and HIO, the rule for oxoacids is that have the same number of oxygens and hydrogens but different elements (Cl vs Br vs I), is that the compound with the most electronegative element is the stronger acid. With an increase in the number of O atoms attached to Cl, more electrons are pulled away from OH bond and more weaker becomes the OH bond. It explains that the more electronegative the halogen attached to the O, the more acidic the oxoacid. The hydrogen atom will join with one oxygen atom forming the hydroxyl -OH group.
