Question

Which is more acidic : ClOH ,BrOH ,IOH and why ??

Answer 1

Arrange ClOH,BrOH,IOH in the order of decreasing acid strength. ... In case of oxoacids, the one has moreelectronegative halogen is more acidic. Given acids are ClOH, BrOH,IOH in these acids the oxidation state is the same +1. Therefore the acidiccharacter depends only upon the electronegativity

$\large\red{Question:}$

Which is more acidic : ClOH ,BrOH ,IOH

$\large\blue{Answer:}$
In the case of oxaacids, the one has more electronegative halogen is more acidic.

In all the given acids viz., ClOH ,BrOH ,IOH , the oxidation state is same, which is +1.
So the Acidic nature will depend on the electronegativity.

When the halide is more negative, it will pull the electrons more towards itself resulting in stronger acid.

Here,
The order of decreasing Acidic Strength is :
CIOH > BrOH > IOH

Therefore,
Among CIOH,BrOH,IOH, CIOH is more acidic.
