Which of the following is not a disproportionation reaction?
- A \(\mathrm{Cl}_2(g)+2 \mathrm{OH}^{-}(\mathrm{aq}) \longrightarrow \mathrm{ClO}^{-}(\mathrm{aq})+\mathrm{Cl}^{-}(\mathrm{aq})+\mathrm{H}_2 \mathrm{O}\)
- B \(\mathrm{F}_2(g)+2 \mathrm{OH}^{-}(\mathrm{aq}) \longrightarrow \mathrm{OF}_2(g)+2 \mathrm{~F}^{-}(\mathrm{aq})+\mathrm{H}_2 \mathrm{O}(l)\)
- C \(4 \mathrm{ClO}_3^{-}(a q) \longrightarrow \mathrm{Cl}^{-}(a q)+3 \mathrm{ClO}_4^{-}(\mathrm{aq})\)
- D \(3 \mathrm{ClO}^{-}(a q) \longrightarrow 2 \mathrm{Cl}^{-}(a q)+\mathrm{ClO}_3^{-}(a q)\)
Answer & Solution
Correct Answer
(B) \(\mathrm{F}_2(g)+2 \mathrm{OH}^{-}(\mathrm{aq}) \longrightarrow \mathrm{OF}_2(g)+2 \mathrm{~F}^{-}(\mathrm{aq})+\mathrm{H}_2 \mathrm{O}(l)\)
Step-by-step Solution
Detailed explanation
In disproportionation reaction, oxidation state of one compound convert to the two compounds, one of higher and one of lower oxidation state. In both the compounds, \(\mathrm{F}^{-}\)and \(\mathrm{OF}_2\), oxidation state of \(\mathrm{F}\) is -1 . Hence, fluorine does not…
