Course content

1 section • 8 lectures • 2h 14m total length

  • 13.1. Contents of Organic Compounds containing Nitrogen12:04

    explore the contents of nitrogen-containing organic compounds, focusing on amines, their nomenclature, preparation, physical and chemical properties, aromatic amines, acetylation, and benzylation.

  • 13.2. Introduction of Organic Compounds containing Nitrogen10:29

    Explore nitrogen-containing organic compounds, including amines and nitro groups, cyanides, and nitrates, and learn their functional groups, nomenclature, and key structural features.

  • 13.3. Preparation of Amines27:13

    explores the preparation of amines via alkylation of ammonia with alkyl halides in sealed tubes at 373 kelvin, nitro reduction, and Gabriel synthesis.

  • 13.4. Physical Properties of Amines15:19

    Assess the physical properties of amines, including boiling points, hydrogen bonding, and solubility, and explain how substitution patterns influence basic strength in primary, secondary, and tertiary amines.

  • 13.5. Aromatic Amines16:39

    Explore aromatic amines, where nitrogen attaches to a benzene ring, and learn how the lone pair engages ring resonance to shape basic strength and substituent effects.

  • 13.6. Acylation and benzoylation17:48

    Explore acylation and benzoylation of nitrogen-containing compounds, covering benzylation of primary and secondary amines, acid chloride reactions to form amides, Hofmann and nitro-derivative pathways, and acetylation concepts.

  • 13.7. Diazonium Salt16:21

    Explore diazonium salts in organic compounds containing nitrogen, focusing on disodium salts, their formation from aromatic amines, and their versatile coupling reactions, hydrolysis to phenol, and substitutions with benzene derivatives.

  • 13.8. Cyanides and Isocyanides18:27

    Explore cyanides and isocyanides: their structure and naming, and reactions such as hydrolysis to amides and carboxylic acids, reduction to amines, Grignard reactions, and carbylamine formation.

Requirements

  • The child should have clear concepts of Organic Compounds and their derivative's.

Description

Amines may be regarded as derivatives of ammonia in which one, two or

all three hydrogen atoms have been replaced by alkyl or aryl groups.

Amines are designated as primary (1°), secondary (2°) or tertiary (3°)

according as one, two or three hydrogen atoms in ammonia molecule have

been substituted by alkyl or aryl groups.

Nomenclature of Aliphatic Amines.

(i) Common System. Aliphatic amines are named by prefixing alkyl group

to amine. Mixed secondary or tertiary amines are named as N-substituted

derivatives of the largest group of primary amine. For example, CH3NH2 is

named as methylamine, (CH3)2NH is namzed as dimethylamine and

CH3NHC2H5 is named as methylethylamine.

(ii) IUPAC System. Aliphatic primary amines are named as alkanamines

by removing the final "e" of the name of parent alkane and adding the

suffix 'amine'.

Nomenclature of Aromatic Amines. The simplest aromatic amine is

aniline, IUPAC name is benzenamine. Most of the aryl amines are named

as derivatives of aniline although some of them are given special names

also.

3. Structure of Amines. Nitrogen orbitals in amines are sp3 hybridized

and amines have a pyramidal shape. Due to the presence of a lone pair of

electrons on N atom, C-N-E (where E is C or H) bond angle is slightly

lesser than 109.5°.

In aromatic amines, because of the electron pair, nitrogen can conjugate

with the benzene ring giving carbon nitrogen bond with double bond

character. Thus the C-N bond in aromatic amines is shorter than that in

aliphatic amines.Amines are derivatives of NH3.
