Which one of the following reactions does not occur?

Options

A. `F_(2)+2Cl^(-) to 2F^(-)+Cl_(2)`
B. `Cl_(2)+2F^(-) to 2Cl^(-)+F_(2)`
C. `Na_(3)[Ag(S_(2)O_(3))_(2)]`
D. `Ag_(3)[Na(S_(2)O_(3))_(2)]`

Answer

B

Explanation

The reaction `Cl_(2)+2F^(-) to 2Cl^(-)+F_(2)` is not possible, because a halogen of higher atomic number cannot oxidise a halide of lower atomic number.
