Vedclass · Answer

(B) $Cl_2$,$MnO_4^{2-}$,and $NO_2$ undergo disproportionation in alkaline medium.$1. \, Cl_2 + 2 OH^- \rightarrow Cl^- + ClO^- + H_2 O$$2. \, 3 MnO_4^{2-} + 4 H^+ \rightarrow 2 MnO_4^- + MnO_2 + 2 H_2 O$ (Note: $MnO_4^{2-}$ disproportionates in neutral or acidic medium,but is often cited in context of its instability relative to $MnO_4^-$).$3. \, 2 NO_2 + 2 OH^- \rightarrow NO_2^- + NO_3^- + H_2 O$$ClO_4^-$ does not undergo disproportionation as $Cl$ is already in its highest oxidation state of $+7$.
