What happens in a halogen displacement reaction?

Description : What happens in a halogen displacement reaction?

Last Answer : In a halogen displacement reaction, one halogen displaces another in a compound. Whether or not the reaction occurs depends on the reactivity of the halogens. The order of reactivity is the same as the ... below Cl on the periodic table, so it cannot displace (replace) Cl from the NaCl compound.
