In the reaction 2Br-1 + X2 → Br2 + 2X-1, X2 is

X2 is Cl2In this reaction, we are dealing with the halogen displacement reaction where a halide ion reacts with a halogen molecule. Specifically, the reaction is:2Br- + X2 → Br2 + 2X-Here, the bromine ion (Br-) displaces the halogen (X2) to form bromine gas (Br2) and a new halide ion (X-). Based on the reactivity series of halogens, we know that halogens can displace less reactive halogens. Chlorine (Cl2) is more reactive than bromine (Br2). Therefore, chlorine (Cl2) can displace bromine ions (Br-) from a solution, forming bromine gas and chloride ions (Cl-). So, X2 in this case is chlorine (Cl2).Concept Behind the Reaction:The concept used here is based on the reactivity series of halogens, which dictates that more reactive halogens can displace less reactive halogens from their compounds. The order of reactivity is:Fluorine (F2) > Chlorine (Cl2) > Bromine (Br2) > Iodine (I2)In this reaction, chlorine (Cl2) displaces bromine (Br-) because it is more reactive.

Detailed Solution

X₂ is Cl₂

In this reaction, we are dealing with the halogen displacement reaction where a halide ion reacts with a halogen molecule. Specifically, the reaction is:

2Br^- + X₂ → Br₂ + 2X^-

Here, the bromine ion (Br^-) displaces the halogen (X₂) to form bromine gas (Br₂) and a new halide ion (X^-). Based on the reactivity series of halogens, we know that halogens can displace less reactive halogens. Chlorine (Cl₂) is more reactive than bromine (Br₂). Therefore, chlorine (Cl₂) can displace bromine ions (Br^-) from a solution, forming bromine gas and chloride ions (Cl^-). So, X₂ in this case is chlorine (Cl₂).

Concept Behind the Reaction:

The concept used here is based on the reactivity series of halogens, which dictates that more reactive halogens can displace less reactive halogens from their compounds. The order of reactivity is:
