A

`HClO gt HBrO gt HIO`

B

`HIO gt HBrO gt HClO`

C

`HBrO gt HIO gt HClO`

D

`HClO gt HIO gt HBrO`

Text Solution

Verified by Experts

The correct Answer is:
A
In oxy-acids, more the electronegativity, more is the acid strength. Electronegativity of Cl, Br and I is in the order Cl gt Br gt I. Therefore acid strength is also in the same order I.e.. HClO gt HBrO gt HIO.
