But then, I read somewhere that $\ce{HBrO4}$ is stronger than $\ce{HIO4}$, because in this case it's electronegativity that plays the important role. The octet rule is the core concept of bonding which emphasizes that every element should have 8 valence electrons to be considered stable. This is because the more electronegative the halogen attached, the more electron withdrawing it is from the O-H bond. Here bromine atom after bonding has more than 8 valence electrons. As the hybridization is sp3 and geometry is tetrahedral, it is around 120 degrees or less than that. HBrO2 is the stronger acid. Weakening of the O-H bonds leads to increased.
