Question

How many of the following shows disproportionation reactions?

H₂O, Ag, Cu⁺, K⁺, F₂, Cl₂, ClO₃^-

Answer 1

Atom in its highest or lowest oxidation state does not disproportionate.

H₂O₂, Cu⁺, Cl₂, ClO₃^-

H₂O₂ → O^-1 can go to O^2- and O₂

Cu⁺  → Cu = +1 to +2 and 0

^oCl₂ → to Cl^-1 and +1, +3, +5, +7

Cl⁺⁵O₃^- → Cl^-1 and Cl⁺⁷
