Question

Write the chemical equation of the following reaction:
(a) Swarts reaction
(b) Sandmeyers reaction

Answer 1

Hint: Generally alkyl fluorides are going to prepare from alkyl chlorides using Swarts reaction. Aryl halides are prepared from benzene diazonium chloride using copper salt, this reaction is called Sanmeyers reaction.

Complete answer:
- In the question it is given to write about the Swarts reaction and Sandmeyers reaction.
Swarts reaction:
Alkyl bromide or alkyl chlorides are going to react with metallic fluorides like AgF, $Co{{F}_{2}},H{{g}_{2}}{{F}_{2}}$ and gives respective alkyl halide as the product.

In the above chemical reaction ethyl chloride reacts with silver fluoride and forms ethyl fluoride and silver chloride as the products.
Sandmeyers reaction: This chemical reaction is named after Traugott Sandmeyer.
It is an example for radical nucleophilic substitution reactions. Here copper salts are going to act as catalysts.
Benzene diazonium chloride is going to react with cuprous halides in the presence of an acid and forms aryl halides as the products.

In this chemical reaction we have to use freshly prepared benzene diazonium chloride to carry out the reaction.
In the above chemical reaction benzene diazonium chloride reacts with copper bromide (I) in the presence of HBr and forms bromo benzene and nitrogen gas are the products.

Note:
In industry Swarts reaction and sandmeyer's reactions have a lot of applications to prepare various products. These reactions are called named reactions. By using these two reactions a variety of halides are going to get prepared.
