Question

Consider the following reaction.

• A. It is not a disproportionation reaction
• B. It is intramolecular redox reaction
• C. $O{H}^{-}$ is reducing as well as oxidising agent
• D. $(CHO{)}_2$ is a reducing as well as oxidising agent

Answer 1

The correct option is C $O{H}^{-}$ is reducing as well as oxidising agent

In $H-\underset{\underset{O}{||}}{C}-\underset{\underset{O}{||}}{C}-H$, in the presence of $O{H}^{-}$. One $CHO$ is oxidised to $CO{O}^{-}$ and other $CHO$ is reduced to $C{H}_{2}OH$. Thus, it is not a disproportionation reaction as reduction and oxidation happens within a molecule and therefore it is intramolecular redox reaction. Also, intramolecular redox reaction occurs when we have the oxidizing and reducing agents within one molecule. Thus,$H-\underset{\underset{O}{||}}{C}-\underset{\underset{O}{||}}{C}-H$ is reducing as well as oxidising agent.
