Which type of reaction is represented by the generic equation AB + CD mc002-1.jpg AD + CB?
This equation represents a Double Displacement Reaction.
Explanation:
Given equation is,
AB + CD → AD + CB
In above reaction A and C are switching their groups i.e. B and D. A has given off B to C and C has given D to A. Such reactions in which the cations and anions of two compounds are exchanged are called double displacement or double replacement reactions.
Double Displacement Reaction
A double displacement reaction is a type of chemical reaction where two compounds react by exchanging ions to form new compounds. In this reaction, the positive ions and negative ions of the two compounds switch places with each other.
For example, in the equation AB + CD → AD + CB, compound A and C exchange their ions with compound B and D respectively. The products formed are compound AD and CB.
Double displacement reactions are also known as double replacement reactions. They often occur in aqueous solutions where the ions are free to move and exchange partners.
This type of reaction is characterized by the formation of a precipitate, gas, or water as a product. Precipitation reactions and acid-base neutralization reactions are common examples of double displacement reactions.
Overall, double displacement reactions play an important role in chemistry and are used in various fields to synthesize new compounds and study the behavior of different substances.
