Question

What is the difference between double displacement reaction and displacement reaction

Answer 1

A single-displacement reaction, also called single-displacement reaction, is a type of oxidation-reduction chemical reaction when an element or ion moves out of one compound and into another. (One element is replaced by another in a compound.) This is usually written as... 
'A + BC → AC + B' 
Definition: A double displacement reaction is a type of reaction where part of of one reactant is replaced by part of another reactant. 

Double displacement reactions take the form: 

AB + CD → AD + CB 
Examples: 
The reaction 

AgNO3 + NaCl → AgCl + NaNO3 

is a double displacement reaction. The silver traded its nitrite ion for the sodium's chloride ion.

Answer 2

♥ Displacement reaction :- Such a reaction in which a highly reactive element displaces the less reactive element from it's salt solution .

E.g :- Fe + CuSO4 ---> FeSO4 + Cu

♥ Double-Displacement reaction :- Such a reaction in which there is an exchange of ions between the reactants to form new compound .

E.g :- BaCl2 + Na2SO4 ---> BaSO4 + 2NaCl
