(i) Which of the following species, do not show disproportionation reaction and why?CIO– , CIO2– , CIO3– and CIO4–Also write reaction for each of the species that disproportionate.(ii) Give one example each of the following redox reaction:(a) Combination reaction(b) Decomposition reaction(c) Metal displacement reaction |

Answer» (i) Among the oxoanions of chlorine, CIO4– does not disproportionate because in this oxoanion. Chlorine is present in its highest oxidation state i.e. +7. The disproportionation reactions for other there oxoanions of chlorine are as follows: \(3\overset{+1}{CI}O^-\rightarrow2\overset{-1}{Cl}+\overset{+5}{CIO^-_3}\) \(6\overset{+3}{CI}O^-_2 \overset{hr}{\rightarrow}4\overset{+5}{CI}O^-_3+2\overset{-1}{Cl^-}\) \(4\overset{+5}{CI}O^-_3\rightarrow\overset{-1}{Cl^-}+3\overset{+7}{CI}O^-_4\) (ii) (a) Example of combination reaction 3Mg(s) + N2(g) → Mg3N2(s) (b) Example of Decomposition reaction: 2NaH(s) \(\overset{\Delta}{\rightarrow}\) 2Na(s) + H2(g) (c) Example of metal displacement reaction: V2O5(s) + 5Ca(s) \(\overset{\Delta}{\rightarrow}\) 2V(s) + 5CaO(s) |
