In which one of the following sets all species show disproportionation reaction?
- A \(\mathrm{ClO}_{2}^{-}, \mathrm{F}_{2}, \mathrm{MnO}_{4}^{-}\)and \(\mathrm{Cr}_{2} \mathrm{O}_{7}^{2-}\)
- B \(\mathrm{Cr}_{2} \mathrm{O}_{7}^{2-}, \mathrm{MnO}_{4}^{-}, \mathrm{ClO}_{2}^{-}\)and \(\mathrm{Cl}_{2}\)
- C \(\mathrm{MnO}_{4}^{-}, \mathrm{ClO}_{2}^{-}, \mathrm{Cl}_{2}\) and \(\mathrm{Mn}^{3+}\)
- D \(\mathrm{ClO}_{4}^{-}, \mathrm{MnO}_{4}^{-}, \mathrm{ClO}_{2}^{-}\)and \(\mathrm{F}_{2}\)
Answer & Solution
Correct Answer
(C) \(\mathrm{MnO}_{4}^{-}, \mathrm{ClO}_{2}^{-}, \mathrm{Cl}_{2}\) and \(\mathrm{Mn}^{3+}\)
Step-by-step Solution
Detailed explanation
No option contains all species that show disproportionation reaction. \(\mathrm{MnO}_{4}^{-}\) \(Mn\) is in \(+7\) oxidation state (highest) hence cannot be simultaneously oxidized or reduced
