Answer #1

the large rvalue of Ka means that it is more acidic in nature and easily releases proton.

As oxygen is more electronegative than the halogens , it attracts the electron of oxygen halogen bond towards itself .

As the electronnegativity decreases from Cl to I the shared pair of electron of oxygen_halogen bond moves closer and closer to the oxygen atom .

consequently electron density on oxygen increases from Cl to I and we can say that
the proton release in HClO2 is easily take place while in HIO2 it does not.

so the HClO2 is having largest Ka value .
