When chlorine (as a gas or dissolved in water) is added to sodium bromide solution, the chlorine takes the place of the bromine. Because chlorine is more reactive than bromine, it displaces ...

A halogen cannot displace itself from a solution of one of its salts, eg potassium bromine would not displace bromine water, so these combinations are not done.
