Question 11 Achieve

[205873468]

In this question we are asked to list oxoacids according to strength in acidity, but I am a bit confused on how to determine this. Why is HClO more acidic than HBrO? I know that HCLo4 is a strong acid but so is HBr, so how can we determine which is more acidic? I am a bit confused.

Cl has a larger electronegativity than Br, so it has more electron density around it, rather than near the H. Therefore it’s a stronger acid, since the H is more able to break free

HClO is more acidic than HBrO because of the difference of electronegativity between the two. HClO is more electronegative than HBrO, which makes it a stronger acid.
