Question
Why does chlorine displace bromine in a reaction with potassium bromide?
Answer
Chlorine is more reactive than bromine, which allows it to displace bromine from potassium bromide. The reactivity of halogens decreases down the group, making chlorine a stronger oxidizing agent compared to bromine.
Explanation
This answer is strong as it explains the concept of reactivity in halogens and provides a rationale for the displacement reaction. The question assesses the student's understanding of the trends in reactivity within Group 7 elements.
Common mistake
Misunderstanding Displacement Reactions
Students often think that halogens can displace any halide salt regardless of their reactivity.
Remember that a more reactive halogen can displace a less reactive halide from its salt, while a less reactive halogen cannot displace a more reactive one.
