Which reagent is 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 is the role of NaNO2?
Sodium nitrite is an inorganic sodium salt having nitrite as the counterion. Used as a food preservative and antidote to cyanide poisoning. It has a role as an antimicrobial food preservative, an antihypertensive agent, a food antioxidant, a poison and an antidote to cyanide poisoning.
Is important reagent of diazotization reaction?
The diazotization reaction mechanism begins with the reaction of nitrous acid with the other acid to give water and nitrosonium ion. Thus, the required nitrosonium ion is formed….Uses of Diazonium Compounds.

Which compound does not show diazotization reaction?
Benzylamine is a 1∘ aliphatic amiine and hence does not undergo diazotisation.
Is NaNO2 a strong base?
Since HNO2 (aq) is only a weak acid, NO2 – will act as a weak base. Therefore, the solution of NaNO2 will be basic.
What is the name of NaNO2?

What is diazotization write diazotization of aniline?
Solution 2 Diazotisation: The process of conversion of a primary aromatic amino compound into a diazonium salt, is known as diazotisation. This process is carried out by adding an aqueous solution of sodium nitrite to a solution of primary aromatic amine (e.g., aniline) in excess of HCl at a temperature below 5°C.
Does paracetamol undergo diazotization?
The hydrolyzed product of paracetamol is diazotized with nitrite in acidic standard at room temperature and the diazonium salt thus shaped is coupled with 1,3 dinitrobenzene and 2,4 dinitrophenyl hydrazine to give colored azo dye in alkaline standard is the source for the determination of paracetamol.
What is an example of a diazotization reaction?
An example of a diazotization reaction is given below. In the example illustrated above, it can be noted that nitrous acid is generated from the reaction between the sodium nitrite and the other mineral acid (acid derived from one or many inorganic compounds) which is present in excess.
Does phenylamine dissociate in diazotization reaction?
No, because we need the reagent HNO2 (nitrous acid) in this diazotization reaction. NaNO2 contains NO2- (nitrite) ions which react with the acid that is used to dissolve the phenylamine (e.g. HCL) to form HNO2 in the following reaction: H+ + NO2- -> HNO2. This reaction occurs in situ.
What are the applications of diazonium salts in nanotechnology?
Diazonium Salts are found to be useful in the Fischer Indole Synthesis process because they can be reduced to hydrazine derivatives with the help of stannous chloride. They are used as standard reagents while synthesizing organic compounds. Diazonium salts have the potential to have applications in the field of nanotechnology.
What is an alternate method of preparing sodium nitrate?
Therefore, an alternate method of preparing sodium nitrate is by reacting sodium hydroxide with ammonium nitrate instead of nitric acid. The chemical reaction is: Alternately, ammonium nitrate can be reacted with sodium carbonate or sodium bicarbonate.
