Which one is the correct observation when `Br_(2)` is treated with NaF, NaCl and NaI taken in three test tubes labelled as (I), (II) and (III) ?

A

1. `F_(2)` is liberated in (X) and `Cl_(2)` in (Y).

B

2. Only `I_(2)` is liberated in (Z).

C

3. Only `Cl_(2)` is liberated in (Y).

D

4. Only `F_(2)` is liberated in (X).

Text Solution

Verified by Experts

The correct Answer is:
B
More reactive halogen can displace less reactive halogen from its salt solution. `F_(2)` can displace `Cl_(2), Br_(2), I_(2)` from their salt solutions while `Cl_(2)` can displace `Br_(2) and I_(2)` from NaBr and Nal. `Br_(2)` can displace only `I_(2)` from Nal.
`2NaI+Br_(2)rarr2NaBr+I_(2)`
