Question

Differentiate between displacement reaction and double displacement rea tion

Answer 1

Definition
Displacement Reaction: A displacement reaction is a chemical reaction where a chemical species in a molecule is replaced by another chemical species.

Double Displacement Reaction: A double displacement reaction is a chemical reaction that involves the exchange of two ionic species between two different molecules.

Displacement
Displacement Reaction: In displacement reactions, one chemical species is displaced.

Double Displacement Reaction: In double displacement reactions, two chemical species are displaced.

Replacement
Displacement Reaction: In displacement reactions, one chemical species is replaced.

Double Displacement Reaction: In double displacement reactions, two chemical species are replaced.

Reactivity
Displacement Reaction: Displacement reactions occur based on the reactivity of chemical species.

Double Displacement Reaction: Double displacement reactions occur where exchangeable ions are included in compounds.

Conclusion
Double displacement reactions are a type of displacement reactions. In both reactions, a displacement and a replacement occur at the same time. The main difference between displacement and double displacement reaction is that in displacement reaction, a single chemical species is replaced whereas in double displacement reactions, two chemical species are replaced.

Answer 2

In displacement reaction one element displaces displaces another element from the compound.

In double displacement reaction negative and positive radical of the reactant are interchanged
