Question

_______ chemical reaction is also known as the substitution reaction.

Answer 1

• Single displacement- A displacement reaction is the one wherein the atom or a set of atoms is displaced by another atom in a molecule.
• The general representation of displacement reaction is A + B-C → A-C + B
• The above equation exists when A is more reactive than B.
• For instance, when iron is added to a copper sulfate solution, it displaces the copper metal.
• $\underset{\mathrm{Iron}}{\mathrm{Fe}\left(\mathrm{s}\right)}+\underset{\mathrm{Copper}\mathrm{sulphate}}{\mathrm{CuSO}4\left(\mathrm{aq}\right)}\to \underset{\mathrm{Ferrous}\mathrm{sulphate}}{\mathrm{FeSO}4\left(\mathrm{aq}\right)}+\underset{\mathrm{Copper}}{\mathrm{Cu}\left(\mathrm{s}\right)}$
• As there is a substitution of iron, this type of reaction is also known as a substitution reaction.

Hence, a single displacement chemical reaction is also known as the substitution reaction.
