What is the difference between displacement and double displacement reactions? Write equations for these reactions.

Ques 13: What is the difference between displacement and double displacement reactions? Write equations for these reactions. 

 Ans 13: In a displacement reaction, a more reactive element replaces a less reactive element from a compound.   

              A + BX → AX + B,      where A is more reactive than B

In a double displacement reaction, two atoms or a group of atoms switch places to form new compounds. 

                 AB + CD → A D + BC

For example:

Displacement reaction:

Double displacement reaction:
