When `Br_2` is treated with aqueous solutions of NaF, NaCl and NaI separately

Options

A. `F_(2), Cl_(2) and I_(2)` are liberated
B. Only `F_(2) and Cl_(2)` are liberated
C. only `I_(2)` is liberated
D. only `Cl_(2)` is liberated

Answer

C

Explanation

`Br_(2)` being a stronger oxidising agent displaces a weaker oxidising agent `(I_(2))` from its salt (NaI).
`2NaI + Br_(2) rarr 2 NaBr + I_(2)`
