How do you make Benzenediazonium chloride?

Benzenediazonium chloride can be formed by first mixing benzene with nitric acid in the presence of sulfuric acid, which forms nitrobenzene. Nitrobenzene can then be transformed into aniline and aniline can be mixed with nitrous acid in the presence of hydrochloric acid to form the benzenediazonium chloride molecule.

What is diazonium salt give its preparation?

How are diazonium salts formed? In the presence of hydrochloric acid, diazonium salts are produced by taking an alkyl or aryl primary amine and adding to it with sodium nitrite. Example reactions involving diazonium salts are: Sandmeyer reaction: synthesis of an aryl chloride through the action of copper (I) chloride.

What product is formed from the reaction of p Methylphenol with Benzenediazonium chloride?

Answer and Explanation: The reaction between p-methyl phenol and benzene diazonium chloride results in the formation of azo compound.

What happens when Benzenediazonium chloride is heated with water?

When benzene diazonium chloride is heated with water, it produces phenol as well as nitrogen gas and hydrochloric acid as by-products.

How do you produce nitrous acid in situ?

Nitrous acid is usually generated by acidification of aqueous solutions of sodium nitrite with a mineral acid. The acidification is usually conducted at ice temperatures, and the HNO2 is consumed in situ. Free nitrous acid is unstable and decomposes rapidly.

What is diazotization preparation of Benzenediazonium chloride and diazotization reaction mechanism?

Preparation of benzenediazonium chloride Benzene diazonium chloride is prepared by aniline. When aniline reacts with nitrous acid under low temperature (0-50C), benzenediazonium chloride is given as the product. If temperature is increased benzene diazonium chloride decomposes to phenol.

What is the reagent used for diazotization?

First, let’s go through formation of the diazonium salt, a process called “diazotization”. The first key reagent for this process is either sodium nitrite (NaNO2) or nitrous acid (HNO2). Sodium nitrite has the advantage of being an easily handled salt, while HNO2 is a somewhat unstable liquid.

What organic product is formed by reacting a diazonium salt with water at elevated temperature?

The diazonium ion reacts with the water in the solution and phenol is formed – either in solution or as a black oily liquid (depending on how much is formed). Nitrogen gas is evolved.

Which of the following will be most stable diazonium salt?

Among the given diazonium salts, benzene diazonium halide C6H5N2+X− is most stable due to conjugation of the N≡N triple bond with benzene ring.

When benzenediazonium chloride is treated with water the compound formed is?

phenol
When benzenediazonium chloride is treated with water, the diazonium group is replaced by −OH group and phenol is obtained.

When benzenediazonium chloride is warmed with methanol the product formed is?

Solution : On warning an aqueous solution of benzenediazonium chloride , phenol is formed.
