Displacement Reactions - Examples

Less reactive halogens can be displaced by more reactive halogens from compounds. In other words, it takes the place of the less reactive element. Below are some examples of different types of displacement:

Substitution

The substitute takes the place on the pitch of the other footballer, replacing him in the team.

Cannonball

By bombing into the water, this person displaces (replaces) some of the water in the swimming pool.
