Diazotization
Easychemistry
Diazotization of aniline produces:
Select the correct option:
Solution
Incorrect! Answer:
Benzenediazonium chloride
Diazotization is the reaction of a primary aromatic amine with nitrous acid (HNO2).
- Reagents: NaNO2 and HCl at 0−5∘C.
- Reaction: C6H5NH2+NaNO2+2HCl→C6H5N2+Cl−+NaCl+2H2O
- Product: Benzenediazonium chloride.
- The low temperature is critical because diazonium salts are thermally unstable and decompose above 5∘C to release N2 gas. These salts are important intermediates for Sandmeyer, Gatterman, and Coupling reactions.
