The hydrolysis of a diazonium salt involves the replacement of the diazo group (-N2+) with a hydroxyl group (-OH). This reaction typically occurs in acidic conditions, forming a phenol and evolving nitrogen gas as a byproduct. For example, the hydrolysis of a diazonium salt like benzene diazonium chloride (C6H5N2Cl) in the presence of water and acid would yield phenol (C6H5OH) and nitrogen gas (N2) as products.

Why aryl diazonium salt are more stable then alkyl diazonium salt?
Aryl diazonium salts are more stable because the aromatic ring stabilizes the positive charge on the nitrogen atom through resonance, spreading the charge over a larger area. In contrast, alkyl diazonium salts lack this resonance stabilization, making them less stable.
Why is it essential to keep the diazonium salt at zero degrees while you are forming the sodium 2-naphthoxide?
Keeping the diazonium salt at zero degrees helps prevent its decomposition, which is a highly exothermic reaction. The low temperature helps control the rate of reaction and ensures the stability of the diazonium salt. This is crucial for the successful formation of the sodium 2-naphthoxide and minimizes unwanted byproducts.
Why must the diazonium salt be kept cold?
Diazonium salts are unstable and can undergo decomposition to form highly reactive species. By keeping them cold, the reaction rate is reduced, which helps to minimize side reactions and increase the selectivity of the desired reaction. Additionally, the cold temperature helps to prevent the diazonium salt from decomposing prematurely.
How does sulphuric acid prevent hydrolysis of mohr salt and acetic acid prevent hydrolysis of lead acetate?
Sulfuric acid prevents the hydrolysis of Mohr's salt by maintaining a low pH environment, which inhibits the cleavage of the complex ions in the salt. Acetic acid prevents the hydrolysis of lead acetate by acting as a buffer and maintaining a constant pH, which helps stabilize the complex ions in the salt and prevent them from breaking apart.
How do you Prepare sulphanilic acid from phenyl amine?
Sulphanilic acid can be prepared from aniline by diazotization with sodium nitrite in acidic conditions to form diazonium salt, followed by heating or treatment with sulfur dioxide gas to convert the diazonium salt to sulphanilic acid.

What is the purpose of the HCl in diazonium salt formation?
HCl is used in the formation of diazonium salt to protonate the amine group of the primary aromatic amine, making it more reactive towards subsequent reactions. Additionally, HCl helps to promote the diazotization reaction by stabilizing the diazonium cation formed.
What does Hydrolysis give?
hydrolysis gives glucose and fructose
What are alkyl diazonium salts?
Alkyl diazonium salts are organic compounds containing the diazonium functional group (-N2+X-), where X is an anion. They are unstable and highly reactive due to the presence of the diazo group, making them useful intermediates in organic synthesis for the preparation of various carbon-carbon bond-forming reactions. However, they are typically handled with caution due to their explosive nature.

What is the purpose of the NaNO2 when preparing the Pauly reagent?
In the presence of sodium nitrite and hydrochloric acid, sulfanilc acid form a diazonium salt. This salt react with and is an indicator for thyrosine, histidine.

Sulphanilic acid can be prepared from aniline by diazotization with sodium nitrite in acidic conditions to form diazonium salt, followed by heating or treatment with sulfur dioxide gas to convert the diazonium salt to sulphanilic acid.
What would take place when the reaction is heated in the diazotization step?
When the reaction is heated in the diazotization step, the primary aromatic amine reacts with nitrous acid to form a diazonium salt. This is a key intermediate in the synthesis of various aromatic compounds such as azo dyes, which are widely used in the textile industry. Heating is necessary to promote the formation of the diazonium salt.
What is hydrolysis of salts in water?
This is a "reaction" with water, a dissociation of the salt in ions.
