    2Thank You

    Prince Jaat 8 years ago

    Ethylamine and aniline can be distinguished using the azo-dye test. A dye is obtained when aromatic amines react with image069 NCERT Solutions class-12 Chemistry Amines part 1at image070 NCERT Solutions class-12 Chemistry Amines part 1, followed by a reaction with the alkaline solution of 2-naphthol. The dye is usually yellow, red, or orange in colour. Aliphatic amines give a brisk effervescence due (to the evolution of image071 NCERT Solutions class-12 Chemistry Amines part 1gas) under similar conditions.
