Displacement reaction:-

The reaction in which the place of the ion of a less reactive element in a compound is taken by another more reactive element by formation of its own ions, is called displacement reaction.

Double Displacement reaction:-

The reaction in which the ions in the reactants are exchanged to form a precipitate are called double displacement reactions.
