Final answer:
It is true that HBrO2 is a stronger acid than HBrO because the additional oxygen atoms in HBrO2 increase its acidity by weakening the O-H bond.
Step-by-step explanation:
The statement that HBrO2 is a stronger acid than HBrO because HBrO2 has more oxygen atoms bonded to bromine is True. This is because, in oxyacids, the presence of additional oxygen atoms increases the electronegativity around the central atom, which in turn pulls electron density away from the O-H bond, making it weaker. As a result, the O-H bond is more easily dissociable, and the acid can donate a proton more readily, which is a characteristic of a strong acid. This principle is observed not only with bromine oxyacids but also in the case of sulfuric acid and sulfurous acid, where the former is a stronger acid due to additional oxygen atoms.
