Question

explain single displacement and double displacement reaction with examples. ​

Answer 1

The reaction in which an atom or a set of atjms are displaced by another atom in a molecule is called displacement reaction. For when Iron is added to a copper sulfate solution, it displaces the copper metal.

A + B – C → A – C + B

The above equation exists when A is more reactive than B.

The reaction in which two atms or a group of atms are displaced by another atom in a molecule is called a double displacement reaction.

A-B + C-D → A-C + B-D

A and B have to be either:

Halogens where C indicates a cation.

Different metals where in C indicates an anion.
