The diazonium group is a functional group represented by the structure -N₂⁺X⁻, where X is an anion. In arenediazonium ions, the diazonium group is attached to an aromatic ring. The stability of arenediazonium ions is related to resonance. The diazonium ion can undergo resonance stabilization by delocalizing the positive charge onto the aromatic ring. This resonance contributes to the overall stability of the ion, making arenediazonium ions relatively stable. The resonance stabilization reduces the reactivity of the diazonium group and affects its behavior in various synthetic transformations, including the preparation of aromatic compounds and azo dyes.

The basic strength of alkyl amines in aqueous solution is influenced by the interplay of inductive effect, solvation effect, and steric hindrance. The inductive effect of alkyl groups stabilizes the positive charge on the nitrogen, enhancing basicity. Solvation effect involves the interaction of the amine with water molecules, impacting its basic strength. Small alkyl groups facilitate solvation, reinforcing basicity. Steric hindrance, caused by larger alkyl groups, hinders solvation and reduces basicity. Hence, the overall basic strength is a balance of these factors, with inductive effect and solvation promoting basicity, while steric hindrance diminishes it.
