Among the following halogens \(\mathrm{F}_2, \mathrm{Cl}_2, \mathrm{Br}_2\) and \(\mathrm{I}_2\) Which can undergo disproportionation reaction?
- A Only \(I_2\)
- B \(\mathrm{Cl}_2, \mathrm{Br}_2\) and \(\mathrm{I}_2\)
- C \(\mathrm{F}_2, \mathrm{Cl}_2\) and \(\mathrm{Br}_2\)
- D \(\mathrm{F}_2\) and \(\mathrm{Cl}_2\)
Answer & Solution
Correct Answer
(B) \(\mathrm{Cl}_2, \mathrm{Br}_2\) and \(\mathrm{I}_2\)
Step-by-step Solution
Detailed explanation
\(F_2\) do not disproportionate because fluorine do not exist in positive oxidation state however \(\mathrm{Cl}_2, \mathrm{Br}_2 \& \mathrm{I}_2\) undergoes disproportionation.
