Strength of Acids

Postby rachelle1K » Thu Dec 05, 2019 9:06 pm

So on homework problem 6C 19 part c it asks for thee stronger acid between HBrO2 and HClO2. Can someone explain to me why the answer is HClO2? I thought that because bromium's electronegativity is lower is would be more willing to give up H and therefore be a stronger acid.

Both anions would have resonance, but Chlorine's higher electronegativity makes the anion more stable. As a result HClO2 is the stronger acid.

Since Cl has a higher electronegativity, it will pull the electron pair it shares with the hydrogen closer to it, so the H will more easily dislocate and be donated to another molecule

Just to add on to the discussion above:
I find this on google and I think it explained the concept well: ... d-strength
Hope this helps!!!
