Question

Which reaction is not feasible :-

$2KI + Br_2 \to 3KBr + I_2$

$2KBr + I_2 \to 2KI + Br_2$

$2KBr + CI_2 \to 2KCI + Br_2$

$2H_2O + 2F_2 \to 4HF + O_2$

Answer

$2KBr + I_2 \to 2KI + Br_2$

Explanation

Solution

$2KBr + I_2 \longrightarrow 2KI + Br_2$ 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 bromine and iodine, chlorine can displace bromine and iodine and bromide can displace iodine from their salts.
