The diazonium salts (di refers to ‘two’, azo is indicative of ‘nitrogen’ and ium implies that it is cationicin nature), or diazonium compounds, are Hence, they have two nitrogen atoms with one being charged. Benzenediazonium chloride (C6H5N2+Cl–), benzene diazonium hydrogen sulfate … See more WebAdditionally, azo dyes can be made via reaction of diazonium salts with other primary aromatic amines. In that way, azo dyes which can be diazotized into diazonium ions to react with PANI can be produced. By changing the reactants (primary aromatic amines, Scheme 5) of the azo dyes, single linkage combinatorial modification can be achieved ...

Solution: (i) If the pK b value of any base or compound is higher than that of another, it implies that the former is a weaker base than the latter. In aniline, the N-atom is ... WebAn “arenediazonium salt” is formed by the reaction of an aromatic amine with nitrous acid at 0–5°C, and has the structure shown below.

Primary aromatic amines react with nitrous acid at 0 o C to give a diazonium salt. Nitrous acid is in turn formed by the reaction of sodium nitrite with hydrochloric acid. The active reagent is nitrous anhydride or dinitrogen trioxide. natural phosphates
