The reagent combination of HONO (nitrous acid) and 1-10-naphthol is commonly used for the detection of primary amines. When a primary amine is present, it reacts with HONO to form a diazonium salt, which then reacts with 1-10-naphthol to form a brightly colored azo dye. Secondary and tertiary amines will not react with HONO under these conditions, so this test can be used to distinguish between the pair of compounds. None of the other reagents listed would specifically interact with primary amines.
