Why is HBrO a weaker acid than HBrO3? A. The HO bond in HBrO is less polar than the HO bond in HBrO3 B. The HO bond in HBrO is more polar than the HO bond in HBrO3 C. The HBr bond in HBro is weaker than the HBr in HBrO3 D. The HBr bond in HBrO is stronger than the HBr bond in HBrO3 E. The HO bond in HBrO is weaker than the HO bond in HBrO3

The answer is B!!!

Hope this helps :D

(Chemistry was hard for me too!)

Ans:  A)

HBrO and HBrO₃ are oxyacids where the acidic strength increases with the increase in the number of atoms attached to the central atom.

In both acids, oxygen is the most electronegative atom. In HBrO, the B atom is linked to only one O atom. In contrast, there are 3 electronegative O atoms surrounding the central B atom in HBrO₃ which would make the OH bond more polar and easily accessible. Thus, HBrO₃ tends to lose a proton readily than HBrO making the former more acidic.
