Which of the following is the strongest oxidising agent?

Options

A. `Br_(2)`
B. `I_(2)`
C. `Cl_(2)`
D. `F_(2)`

Answer

4

Explanation

The correct order of oxidizing power is
`F_(2) gt Cl_(2) gt Br_(2) gt I_(2)`
Fluorine is the strongest oxidising agent . There are two main reason for this,
1. `F_(2)` has a low enthalpy of dissociation which arises from the weakness of the `F-F` bond.
2. `F^(-)` has a high enthalpy of hydration which arises from the high charge density of `F^(-)` ion due to its smaller size.
