Question

Why displacement reaction and double displacement reaction definition?​

Answer 1

$\huge\star\bold\red{Hello!}$

$\large\sf\green{Displacement\:Reaction:-}$

Those reactions in which is more reactive element displaces with less reactive elements from its compound. Such reaction is called as displacement reaction.

Ex- Fe + CuSO4 $\longrightarrow$ FeSO4 +Cu

$\large\sf\purple{Double\:Displacement\:Reaction:-}$

The reaction to which there is exchange of ions between the reactants are called as double displacement reaction.

Ex- Na2SO4 + BaCl2 $\longrightarrow$ BaSO4 + 2NaCl
