Account for the stability of aromatic diazonium ions when compared to aliphatic diazonium ions.

Text Solution

Verified by Experts

`to` Aliphatic diazonium salts which are formed from `1^(@)` - aliphatic amines are highly unstable and liberate nitrogen gas and alcohols.
`to` Aromatic diazonium salts formed from `1^(@)` - aromatic amines are stable for a short time in solution at low temperatures `(0-5^(@)C)`. The stability of arene diazonium ion is explained on the basis of resonance.

when an primay aromatic amine is treated with NaNO_(2)+HCl at 0^(0)-5^(0)C , a diazonium salt is formed and the reaction is called diazo reaction. In this reaction mineral acid must be added to prevent the coupling reaction of diazonium salt with excess of aryl amine. Diazonium salt is highly useful in the synthesis of number of coloured dyes. For the following diazonium ion the decreasing order of reactivity of these ion in azo-coupling rcaction
