Transition metals react with halogen at ...

Transition metals react with halogen at elevated temperature to form halides. The reactivity order of halogens are

A

`F_2 gt Cl_2 gt Br_2 gt I_2`

B

`Cl_2 gt F_2 gt Br_2 gt I_2`

C

`I_2 gt Br_2 gt Cl_2 gt F_2`

D

`Cl_2 lt F_2 gt I_2 gt Br_2`

Text Solution

Verified by Experts

The correct Answer is:
A
The reactivity order is `F_2 gt Cl_2 gt Br_2 gt I_2 as F_2` is most electronegative and reactive element.
