They are represented by the general formulas RNH2 (Primary amines), R2<\/sub>NH or RNHR’ (Secondary amines) as R3<\/sub>N or R NR’ R” or R2<\/sub> NR’ (Tertiary amines).<\/p>\n \u2192 All the three types of amines behave as Lewis bases due to the presence of one unshared electron pair on nitrogen atom.<\/p>\n \u2192 Amines are obtained from nitrocompounds, halides, amides, imides etc.<\/p>\n <\/p>\n \u2192 Primary and secondary amines are involved in intermolecular association due to inter- molecular hydrogen bonding. Tertiary amines have no intermolecular hydrogen bonding due to the absence of H-atom on nitrogen. Hence the boiling points of isomeric amines are in the order. \u2192 The order of basicity of amines in the gaseous phase follows the order : \u2192 In aqueous solution the order of basicity of substituted amines is \u2192 Aliphatic and aromatic primary amines on heating with chloroform and ethanolic KOH form isocyanide or carbylamine which are foul smelling substances. Secondary and tertiary amines do not give this reaction.<\/p>\n \u2192 Benzene sulphonyl chloride (C6<\/sub>H5<\/sub>.S02<\/sub>Cl) is known as Hinsberg’s reagent. It is used to distinguish between primary, secondary and tertiary amines and also to separate the amines from their mixture.<\/p>\n \u2192 -NH2<\/sub> group is ortho and para directing and a powerful activating group in electrophilic substitution reactions of aniline.<\/p>\n \u2192 Diazonium salts have the general formula \u2192 Diazonium salts are very good intermediates for the introduction of – F, – Cl, – Br, – I, – CN, – OH, – NO2<\/sub> groups into the aromatic ring.<\/p>\n \u2192 Alkyl cyanides are alkyl derivatives of hydrogen cyanide and isocyanides are isomers of alkyl cyanides.<\/p>\n \u2192 Alkyl cyanides are usually obtained from alkyl halides, aldoximes and amides. Alkyl isocyanides are formed from alkyl halides by reacting with silver cyanide. Alkyl cyanides are used as intermediates in the multistep organic synthesis.<\/p>\n","protected":false},"excerpt":{"rendered":" Students can go through TS Inter 2nd Year Chemistry Notes 13th Lesson Organic Compounds Containing Nitrogen will help students in revising the entire concepts quickly.
