Oxidation and reduction Disproportionation

Click For Summary
SUMMARY

Disproportionation reactions are defined as redox processes where a single species undergoes both oxidation and reduction. This term derives from the adjective "disproportionate," indicating an unsymmetrical nature in the reaction. Such reactions typically occur with species in a medium oxidation state, allowing for the possibility of oxidation states both above and below this state. Understanding this concept is crucial for analyzing redox reactions in various chemical contexts.

We call reactions in which one species experiences both oxidation and reduction Disproportionation - but why do we chose this particular name?

Thanks. :smile:

The adjective disproportionate means "not proportioned, unsymmertrical, unsuitable to something in bulk, etc". In a redox reaction, if the two species undergoing redox are of the same kind (oxidation number), then we call this reaction as "disproportionation". There is an obvious unsymmetrical nature in this, if you study the reactions. This reaction is characteristic for species which are in a medium oxidation state; if there are oxidation states available below and above this state, disproportionation can be possible.
