Consider the following reaction.
`underset(CHO) underset(|) (CHO) + OH^(-) to underset(CH_(2)OH) underset(|)(COO^(-))`
Select the incorrect statement.

Options

A. It is disproportion reaction.
B. It is intramolecular redox reaction
C. `OH^(-)` is a reducing as well as oxidising agent
D. `underset(CHO) underset(|) (CHO)` is a reducing as well as oxidising agent.

Answer

C

Explanation

Once CHO is oxidised to `COO^(-)` and one CHO is reduced to `CH_(2)OH`.
Thus, it is a disproportionation reaction. Thus, (a) and (b) is true and `overset(CHO)overset(|)(CHO)` is reducing as well as oxidising agent.
Thus, (d) is also true, Thus , ( c) is incorrect.
