INTRODUCING AMINES. This page explains what amines are, and what the difference is between primary, secondary and tertiary amines. It looks in some detail at their simple physical properties such as solubility and boiling points. Details of the chemical reactions of amines are described on separate pages.
Background on the amides, including their physical properties.
AMINES AS BASES. This page looks at the reactions of amines as bases. Their basic properties include the reactions with dilute acids, water and copper(II) ions. It only deals with amines where the functional group is not attached directly to a benzene ring. Aromatic amines such as phenylamine (aniline) are much weaker
Hydrolysing amides under acidic or alkaline conditions, including testing for amides.
OTHER REACTIONS OF AMIDES. This page explains the reason for the lack of basic character in amides, and describes their dehydration to give nitriles, reaction with bromine and sodium hydroxide solution to form primary amines with one less carbon atom (the Hofmann degradation), and their reduction using LiAlH4.
The importance of the lone pair on the nitrogen in the reactions of amines as nucleophiles. Their reactions with halogenoalkanes (haloalkanes or alkyl halides), with acyl chlorides (acid chlorides) and with acid anhydrides. The reaction of amines with nitrous acid (nitric(III) acid) . . . The use of nitrous acid in testing for amines
The reaction with methylamine. We'll take methylamine as typical of primary amines where the -NH2 is attached to an alkyl group. The initial equation would be: The first product this time is called an N-substituted amide. If you compare the structure with the amide produced in the reaction with ammonia, the only difference is
MAKING AMINES. This page looks at the preparation of amines from halogenoalkanes (also known as haloalkanes or alkyl halides) and from nitriles. It only deals with amines where the functional group is not attached directly to a benzene ring. Aromatic amines such as phenylamine (aniline) are usually made differently
MAKING AMIDES. This page describes the preparation of amides from carboxylic acids, acyl chlorides (acid chlorides) and acid anhydrides. Making amides from carboxylic acids. Summary of the process. The carboxylic acid is first converted into an ammonium salt which then produces an amide on heating. The ammonium
The lack of base character in amides, the dehydration of amides to make nitriles, the Hofmann degradation of amides to make primary amines with one less carbon atom, and the reduction of amides. Polyamides . . . A summary of the chemistry of simple polyamides like nylon and Kevlar, including their formation, structure,
