AP Inter 2nd Year Chemistry Notes 13th Lesson Organic Compounds Containing Nitrogen
→ Amines are the derivatives of ammonia and are obtained by replacement of one, two or all the three hydrogen atoms by alkyl groups.
→ If one hydrogen atom of ammonia replaced by alkyl (or) Aryl group 1° – amines are obtained. If two hydrogen atoms of ammonia replaced 2° – amines are obtained. If three hydrogen atoms of ammonia replaced 3° – amines are obtained.
→ Amines are prepared by the reduction of nitro compounds, ammonolysis of alkyl halides, Reduction of amides, Gabriel phthalimide synthesis Hoffmann bromasmide reaction etc.
→ Alkyl amines are stronger bases than ammonia due to +Inductive effect of alkyl groups.
→ Aliphatic (or) Aromatic 1° – amines heating with chloroform and alcoholic kOH to form isocyanides which are foul smelling substance (carbylamie reaction).
→ Aromatic amines react with nitrous acid at 0-5°C temperature to form diazonium salts. This reaction is called Diazotisation.
→ Benzene sulphonyl chloride is known as Hinsberg reagent. Which is used to distinguish 1°, 2°, 3°- amines.
→ Formation of halobenzenes, cyanobenzenes from aromatic diazonium salts in presence of Cu(I)ion is called Sandmeyer reaction.
→ Formation of halobenzenes from reaction of diazonium salt solution with halogen acid in presence of copper powder is called Gatterman reactions.
→ Benzene diazonium chloride reacts with phenol to from P-hydroxy azobenzene. This types of reactions are called coupling reactions.
