Question

`what is substitutional reactions ? explain with two examples `​

Answer 1

Answer:

A substitution reaction is also called a single displacement reaction, single replacement reaction, or single substitution reaction. Examples: CH3Cl reacted with a hydroxy ion (OH-) will produce CH3OH and chlorine. This substitution reaction replaces the chlorine atom on the original molecule with the hydroxy ion.

Answer 2

Answer: The substitution reaction is explained below.

Explanation:

Substitution reaction, also known as single displacement reaction is defined as the chemical reaction in which more reactive element displaces a less reactive element from its chemical reaction.

The reactivity of metal is determined by a series known as reactivity series. The metals lying above in the series are more reactive than the metals which lie below in the series.

A +  BC ⇾ AC + B

Metal A is more reactive than metal B.

For Example:

When zinc granules is added to a solution of copper sulfate solution, the blue color of copper sulfate solution gets decolorized because of the substitution of copper ions with zinc ions.

The chemical equation follows:

$Zn+CuSo_{4}$ → $ZnSo_{4} +Cu$
