Which reaction is not feasible?
  1. A
    2KI + Br2 →\to→ 2KBr + I2
  2. B
    2KBr + I2 →\to→ 2KI + Br2
  3. C
    2KBr + Cl2 →\to→ 2KCl + Br2
  4. D
    2H2O + 2F2 →\to→ 4HF + O2

Correct answer: B

2KBr + I2 →\to→ 2KI + Br2

reaction is not possible because Br– ion is not oxidised in Br2 with I2 due to higher electrode (oxidation) potential of I2 than bromine.
