Syllabus
First assessment 2019
Course
Chemistry 4CH1

Exam points

  • Write balanced equations for halogen displacement, such as chlorine displacing bromide ions.
  • Compare chlorine, bromine and iodine using reaction tables to rank Group 7 reactivity.
  • Predict whether a displacement happens when a halogen is added to a halide solution.

2.7 Halogen displacement reactions question 1

[Maximum number: 3]

This question is about Group 7, the halogens.

When a halogen is added to a solution containing halide ions, a displacement reaction may occur.

The table shows whether a reaction occurs.

Using information from the table, explain the order of reactivity of the three halogens.
