what happens when benzene diazonium chloride is heated with water. and when benzene diazonium chloride is warmed with water it forms – phenol is formed as a product.
What is benzene diazonium chloride?
It is an organic compound.
It is very important organic compound.
It is windly use for the preparation of phenol, nitrobenzene and other important compound.
The concept of benzene diazonium chloride is, it is properly soluble in water. it mean, solubility is good in water.
the chemical formula of benzene diazonium Chloride is [C6H5N2]Cl.
It is used to produce verity of organic compound.
It is windly used in organic chemistry. It is colourless liquid and colourless solid
What happens when benzene diazonium chloride is heated with water?
When benzene diazonium Chloride is warmed with water it forms phenol. after this reaction phenol is formed as a main product and nitrogen gas come out and hydrochloric acid (HCl).
Preparation of diazonium salt (benzene diazonium chloride),
When aniline is treated with NaNO2/HCl. as a result diazonium salt is formed.
When aniline is react with sodium nitrate NaNO2 and (hydrochloric acid) HCl then, it give Diazonium salt as a product.
What happen when diazonium salt is heated?
The main reaction of diazonium salt is a coupling reaction to form a azo compound. it mean, azo dye/azo components is formed by coupling reaction of diazonium salt. let’s understand with the help help of examples.
Coupling reaction with phenol
In this reaction, first phenol is react with benzene diazonium chloride and then it make azo component, it is yellow product, this is called yellow azo dyes.
Coupling reaction with beta naphthol
beta nephthol (napthelene + alcohol = beta nephthol) is react with benzene diazonium chloride then it make azo component. this is called red colour azo dyes.
Coupling reaction with aniline
In this reaction, aniline is directly reacted with benzene diazonium chloride (diazonium salt) and with maintain pH – > 7. then it gives an azo component or azo dye.
Benzene diazonium chloride on hydrolysis gives?
- benzoic acid
When benzene diazonium chloride is treated with water then phenol is formed as a main product. N2 and HCl is also formed.
Benzene diazonium chloride on hydrolysis gives – phenol
Therefore, the correct option is C.
