If you are doing UK A level, you are unlikely to need the structure of nylon-6. In organic chemistry, an amide, also known as an organic amide or a carboxamide, is a compound with the general formula RC(=O)NR′R″, where R, R′, and R″ represent organic groups or hydrogen atoms.. Contents • Naming • Functional Groups • Formulae – types of • Isomerism – types of • Alkanes, alkenes, alkynes (in brief – Level 2 recap) • Physical Properties & Reactions of alkanes and alkenes • Polymerisation – addition & condensation polymerisation (including proteins) Although Amides are important to our Biochemistry they really don't feature much in the A level specification. LEVEL 3 ORGANIC CHEMISTRY . The Amines are the organic chemistry relatives of ammonia: However, in amines, one or more of the hydrogen atoms on the ammonia molecule are replaced by alkyl chains: The alkyl groups on the amines do not have to …

Making amides from acid anhydrides. The amide group is called a peptide bond when it is part of the main chain of a protein, and isopeptide bond when it occurs in a side chain, such as in the amino acids asparagine and glutamine. . Preparation of amines from amides (Edexcel only) This process is often called the Hofmann degradation and can be used to move down a homologous series.

Amides are molecules that contain nitrogen atoms connected to the carbon atom of a carbonyl group. The Amines and Amides The Amines. 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. Modern dyes are formed in a two-stage synthesis: Polyamides . The preparation of dyes from aromatic amines. A-Level Chemistry. Welcome to Topic 17 - CARBOXYLIC ACIDS, AMINES, ESTERS AND ACYLATION.

.

I am including it to show that it is possible to get a polyamide from a single monomer. Revise A-level chemistry with 4college.co.uk .

; Alpha carbon, Cα is directly bonded to the carboxylic group, to an amino group, to a group (R) and to an hydrogen (H).

Primary amides are named by changing the name of the acid by dropping the -oic acid or -ic acid endings and adding -amide.

Nylon-6 is made from a monomer called caprolactam. An acid anhydride is what you get if you remove a molecule of water from two carboxylic acid -COOH groups. As with Amines, it is about how many Hydrogen atoms have been substituted on the Nitrogen atom. Home Specifications > > > > > > Contact Videos Books Extra resources Welcome to 4.7 AMINES.

It is not necessary to include the location number in the name because it is assumed that the functional group will be on the end of the parent chain. ; If the amine group of amino acid and the carboxyl group of a second amino acid react, a bond is created uniting the two amino acids called peptide bond. A-Level Chemistry. Notice that this already contains an amide link. Like amines, various nomenclature rules may be used to name amides, but all include use of the class-specific suffix -amide: Amides can be produced when carboxylic acids react with amines or ammonia in a process called amidation. A summary of the chemistry of simple polyamides like nylon and Kevlar, including their formation, structure, hydrolysis and uses. But you should be able to classify an Amide as Primary or Secondary.

Key Facts & Summary: Amino acids can be defined as carboxylic acids that contain an amine function. Primary amides. For example, if you took two ethanoic acid molecules and removed a molecule of water between them you would get the acid anhydride, ethanoic anhydride (old name: acetic anhydride). AS91391 - Demonstrate understanding of the properties of organic compounds.

The carbonyl carbon is given the #1 location number. Aromatic amines, such as phenylamine, are important industrially for the production of dyes.
