Reaction With Nitrous Acid

The salts of nitrous acid

Write the reactions of aromatic amines with nitrous acid

Which of the following give reaction with nitrous acid ?

Suggest reason why excess mineral acid is used in diazo reaction.

When an primary aromatic amine is treated with NaNO_(2)+HCI at 0^(@)-5^(@)C , a diazonium salt is formed and the reaction is called diazo reaction. In this reaction mineral acid must be added to prevent the coulping reaction of diazonium salt with excess of aryl amine. diazonium salt is highly in the synthesis of number of coloured dyes. In the given reaction. The final product is
