Among the following halogens $\mathrm{F}_{2}, \mathrm{Cl}_{2}, \mathrm{Br}_{2}$ and $\mathrm{I}_{2}$ Which can undergo disproportionation reaction?

Option A:
Only I2
Option B:
$\mathrm{Cl}_{2}, \mathrm{Br}_{2}$ and $\mathrm{I}_{2}$
Correct
Option C:
$\mathrm{F}_{2}, \mathrm{Cl}_{2}$ and $\mathrm{Br}_{2}$
Option D:
$\mathrm{F}_{2}$ and $\mathrm{Cl}_{2}$

Answer: B

Step-by-step solution

$F_{2}$ do not disproportionate because fluorine do not exist in positive oxidation state however $\mathrm{Cl}_{2}, \mathrm{Br}_{2} \& \mathrm{I}_{2}$

undergoes disproportionation.
