Question

which of the following statements is not correct about the reaction given below?
`K_(4)[Fe(CN)_(6)]overset("Oxidation")rarrFe^(3+)+CO_(2)+NO_(3)^(ө)`
A. `Fe` is oxidised from `Fe^(2+)` to `Fe^(3+)`
B. Carbon is oxidised from `C^(2+)` to `C^(4+)`
C. `N` is oxidised from `N^(3-)` to `N^(5+)`
D. carbenes

Answer 1

Correct Answer - D
In `CN^(ө)`, oxidation of `C` is `+2` , and it changes to `+4` oxidation state in `CO_(2)`. So `C` is also oxidised.
