Which of the following reaction is not feasible?

A

`2Kl + Br_(2) rarr 3KBr + I_(2)`

B

`2KBr + I_(2) rarr 2Kl + Br_(2)`

C

`2KBr + Cl_(2) rarr 2KCl + Br_(2)`

D

`2H_(2)O + 2F_(2) rarr 4HF + O_(2)`

Text Solution

Verified by Experts

The correct Answer is:
B
`2KBr + I_(2) +2KI+Br_(2)`
Reaction is not possible because `Br^(-)` ion is not oxidised in `Br_(2)` with `I_(2)` due to higher electrode potential of `I_(2)` than bromine.
In halogens, fluorine can displace chlorine bormine and iodine, chlorine can displace bromine and iodine and bromide can displace iodine from their salts.
