The carbylamine reaction involves the reaction of a primary amine with chloroform (CHCl₃) and an alcoholic KOH solution, resulting in the formation of an isocyanide (carbylamine) along with water and potassium chloride. This reaction is a test for primary amines, producing a foul-smelling isocyanide gas. The distinctive, pungent odor confirms the presence of a primary amine. The carbylamine test is a qualitative method for identifying primary amines, and its application is useful in organic chemistry laboratories for quick and simple amine detection based on the characteristic odor of the isocyanide produced.
Primary aliphatic amines react with nitrous acid (HNO₂) in a process known as the diazotization reaction.

Primary aliphatic amines react with nitrous acid (HNO₂) in a process known as the diazotization reaction. In this reaction, the amine group is converted to a diazonium salt, which is further used for various synthetic transformations. The significance of this reaction lies in its application in the estimation of amino acids and proteins. Amino acids containing primary amine groups undergo diazotization, and the resulting diazonium salt can react with various coupling agents to form colored azo dyes. The intensity of the color can be correlated with the amount of amino acid present, enabling quantitative analysis in protein and amino acid determination.
Aromatic amines react with nitrous acid (HNO₂) in a diazotization reaction, forming diazonium salts. This reaction involves the replacement of the amino group (-NH₂) with a diazo group (-N₂⁺) on the aromatic ring. The diazonium salt is a versatile intermediate used in the synthesis of various aromatRead more
Aromatic amines react with nitrous acid (HNO₂) in a diazotization reaction, forming diazonium salts. This reaction involves the replacement of the amino group (-NH₂) with a diazo group (-N₂⁺) on the aromatic ring. The diazonium salt is a versatile intermediate used in the synthesis of various aromatic compounds. It undergoes coupling reactions with phenols, aromatic amines, and other nucleophiles, leading to the formation of azo dyes, aromatic heterocycles, and substituted aromatic compounds. The diazotization reaction is crucial in organic synthesis, providing a pathway to diversify and functionalize aromatic compounds for applications in dyes, pharmaceuticals, and materials.
Benzenesulfonyl chloride (Hinsberg’s reagent) reacts with primary amines to form sulphonamides. The reaction involves the substitution of the hydrogen atom on the nitrogen of the primary amine with a benzenesulfonyl group (-SO₂Ph). The resulting sulphonamide is insoluble in alkali due to the acidicRead more
Benzenesulfonyl chloride (Hinsberg’s reagent) reacts with primary amines to form sulphonamides. The reaction involves the substitution of the hydrogen atom on the nitrogen of the primary amine with a benzenesulfonyl group (-SO₂Ph). The resulting sulphonamide is insoluble in alkali due to the acidic nature of the sulfonyl group. However, this reaction is selective, as secondary and tertiary amines do not react with Hinsberg’s reagent under mild conditions. The insolubility of the sulphonamide in alkali serves as a useful test in amine classification, allowing differentiation between primary, secondary, and tertiary amines based on solubility behavior.
Benzenesulfonyl chloride (Hinsberg’s reagent) reacts with secondary amines to form sulphonamides.

Benzenesulfonyl chloride (Hinsberg’s reagent) reacts with secondary amines to form sulphonamides. The reaction involves the substitution of a hydrogen atom on the nitrogen of the secondary amine with a benzenesulfonyl group (-SO₂Ph). Unlike primary amines, the resulting sulphonamide is soluble in alkali for secondary amines. This solubility difference arises from the presence of an acidic hydrogen on the nitrogen of secondary amines, allowing the formation of water-soluble salts in alkaline conditions. This reaction and solubility behavior serve as a practical method for distinguishing between primary and secondary amines in organic chemistry.
