Question

Oxidizing action increases in the following order:

• A. $Cl<Br<I<F$
• B. $Cl<I<Br<F$
• C. $I<F<Cl<Br$
• D. $I<Br<Cl<F$

Answer 1

The correct option is D $I<Br<Cl<F$

Halogens can act as oxidising agents by gaining electrons to form halide ions.
As the size of atom increases oxidizing nature decreases because of decreasing electronegativity and decreasing hydration energy.
So, the correct order of oxidizing ability is $I<Br<CI<F$
