Which one of the followign reactions does not occur ?

Options

A. `F_(2)+2CI^(Theta)rarr 2F^(Theta)+CI_(2)`
B. `CI_(2)+2F^(Theta)rarr 2CI^(Theta)+F_(2)`
C. `Br_(2)+2I^(Theta)rarr 2Br^(Theta)+I_(2)`
D. `I_(2)+2Br^(Theta)rarr Br_(2)^(Theta)+2I^(Theta)`

Answer

B, D

Explanation

`CI_(2)` is weaker oxidise agents than `F_(2)` and hence would not oxidice `F^(Theta)` to `F_(2)`. Similarly `I_(2)` is weaker oxidising agent than `Br_(2)` and hence will not oxidse `Br^(Theta)` to `Br_(2)`.
