Hello! I have read (I don't remember the source, and have it only in my notes now) that oxo acids can be strong if Y element has a high electronegativity. If generic formula for oxo acids is HnYOm, than if Y has high electronegativity, it will cause the acid to become strong because Y will be "happy to be on the right side of equation because there are more electorns on the molecule" HnYoM + H2O -> (double arrows here) H3 + Hn-1YOm "the more electronegative Y is the better it can stabilize the Y-O product and the stronger the acid will be. I don't get it. I will be grateful for your help and explanation. For example: HOI is weaker than HOCl O has electronegativity of 3.5, I 2.5, Cl 3.00 I don't see how the above explanation works. What I can assume from the numbers is that O and Cl has a small difference in their electronegativity of 0.5, which might mean that electrons are more or less equally shared between these elements; while the difference between O and I is 1, hence electrons are more likely to be around O. Would it mean that the O-Cl bond is stronger than O-I one and hence it weakens the H-O bond, allowing H to go? Please, help me. Thank you very much!
