Answer:

Displacement reaction

When an atom or group of atoms in a molecule is replaced by another atom or group of atoms, such chemical reaction is called displacement reaction. Displacement reaction is of two types. They are:

  • Single displacement reaction
  • Double displacement reaction

Single displacement reaction

When an atom in a molecule is replaced by another atom, such chemical reaction is called single displacement reaction.

For example:

Zinc + Hydrochloric acid Zinc Chloride + Hydrogen

Zn + 2HCI ZnCI + H

Here, Zn is more reactive than H. So, Zn displaces H from the compound HCI.

Double displacement reaction

A chemical reaction in which the molecules of the reactants get decomposed and exchange their corresponding ions to give new products is called a double displacement reaction.

For example:

AgNO + NaCI NaNO + AgCI

Hope this helps..

Best regards!!
