Displacement reaction:

Displacement reaction is a chemical reaction in which a more reactive element displaces a less reactive element from its compound.

$\sf \: Zn+2HCl⟶ZnCl_2+H_2$

Double displacement reaction:

A type of chemical reaction where two compounds react, and the positive ions (cation) and the negative ions (anion) of the two reactants switch places, forming two new compounds or products is called double displacement reactions.

$\sf \: MgCl_2 +2KOH⟶Mg(OH)_2 +2KCl$
