tell me about oxoacids of halogens?

Expert Answer:

Oxoacids of halogen
The oxoacids of halogens are listed in the given table.

Halic (I) acid

(Hypohalous acid)

HOF

(Hypofluorous acid)

HOCl

(Hypochlorous acid)

HOBr

(Hypobromous acid)

HOI

(Hypoiodous acid)

Halic (III) acid

(Halous acid)

-

-

HOCIO

(Chlorous acid)

-

-

Halic (V) acid

(Halic acid)

-

-

HOCIO2

(Chloric acid)

HOBrO2

(Bromic acid)

HOIO2

(Iodic acid)

Halic (VII) acid

(Perhalic acid)

-

-

HOCIO3

(Perchloric acid)

HOBrO3

(Perbromic acid)

HOIO3

(Periodic acid)

 

Fluorine forms only one oxoacid HOF (Fluoric (I) acid or hypofluorous acid) due to high electronegativity.
Acid strength: HOCl < HClO2 < HClO3 < HClO4
Reason:  HClO4 ? H
HClO4 ? H+  +  ClO4-
                  most stable
 
Acid strength: HOF > HOCl > HOBr > HOI
This is because Fluorine is most electronegative.
