Hint: We need to know that a displacement reaction is the one wherein the atom or a set of atoms is displaced by another atom in a molecule. In a single displacement reaction one element is replaced by another in a compound. The atoms of the more reactive metal push their electrons on to ions of the less reactive metal.
Complete answer:
We have to remember that displacement reaction is a chemical reaction in which a more reactive element displaces a less reactive element from its compound. Both metals and nonmetals take part in displacement reactions. A displacement reaction is the one wherein the atom or a set of atoms is displaced by another atom in a molecule. For instance, when iron is added to a copper sulfate solution, it displaces the copper metal.
The above equation exists when A is more reactive than B.
A and B have to be either:
Halogens where C indicates a cation.
Different metals wherein C indicates an anion.
A single displacement reaction which is also called a single replacement reaction is a kind of oxidation-reduction chemical reaction when an ion or element moves out of a compound, i.e. one element is replaced by the other in a compound. Double displacement reactions occur when a part of two ionic compounds are exchanged and make two new components.
Examples of single displacement reaction can be: reaction between chlorine and sodium bromide.
Chlorine + sodium bromide → sodium chloride + bromine
Example of double displacement reaction can be: Reaction between ferric oxide and hydrochloric acid
Note:
We need to remember that displacement reactions occur when a metal from the electrochemical series is mixed with the ions of a metal lower down in the electrochemical series. The atoms of the more reactive metal push their electrons on to ions of the less reactive metal.
