Question

Give an example of each of the following types of displacement reaction:

The reaction in which a nonmetal displaces another nonmetal.

Answer 1

1. Displacement Reaction

A displacement reaction is defined as a reaction that comprises the replacement of one element from a reactant with an element of another reactant. It is also known as a replacement reaction.

2. Example of displacement reaction

The reaction in which a nonmetal displaces another nonmetal is given as:

$$\begin{gathered} {\mathrm{Cl}}_2\left(\mathrm{aq}\right)+2\mathrm{NaBr}\left(\mathrm{aq}\right)\to 2\mathrm{NaCl}\left(\mathrm{aq}\right)+{\mathrm{Br}}_2\left(\mathrm{aq}\right) \\ \mathrm{Chlorine}\mathrm{Sodium}\mathrm{Sodium}\mathrm{Bromine} \\ \mathrm{bromide}\mathrm{chloride} \end{gathered}$$

Here, Chlorine and Bromine are non-metals. Chlorine is comparatively more reactive than Bromine. Hence, Chlorine displaces the non-metal (bromine) from the compound Sodium bromide. Thus, it is a type of displacement reaction where a nonmetal displaces another nonmetal.
