Organic Chemistry is defined as the study of carbon compounds.

Polymers

Large molecule made from smaller units (monomers) also known as plastics. Polythene is made by using a heated catalyst. Addition polymers from C=C bonds such as polystyrene. Condensation polymers such as nylon. See Polymers

Nomenclature

nomen.jpg

Nomenclature is a system of naming, this is important in organic chemistry. Naming rules based on functional group and homologous series. Counting the number of carbons. Empirical, structural and molecular formulae. See Nomenclature

NMR Spectroscopy

Nuclear Magnetic Resonance Spectroscopy to determine a structure using hydrogen atoms. Different peaks based on different chemical environments. In high resolution splitting occurs producing doublets, triplets etc. See NMR Spectroscopy

Mass and Infra-Red Spectroscopy

Mass spectroscopy uses the mass spectrometer to make fragments, the relative atomic mass of these is used. Infra-red uses the fact different bonds absorb the radiation at different frequencies. These are seen on the graphs. See Mass and Infra-red Spectroscopy

Isomerism

Structural isomers (same formula different structures, chain, position); Geometrical isomers (stereoisomerism, cis trans, spacial arrangement around double carbon); Optical isomers (around a chiral carbon, enantiomers and racemates). See Isomerism

Haloalkanes

haloa.png

A haloalkane is an alkane with a halogen molecule. The C-Hal bond is polar so is susceptibile to nucleophillic attack. The mechanisms for nucleophillic substitution and elimination. And how to determine whether it will happen. See Haloalkanes

Esters

Sweet-smelling compounds producued by reacting a carboxylic acid and alcohol. The alcohol making the acyl group. Esters can be used in flavourings, for instance the sweets pear drops, which give them their distinctive flavour. See Esters

Epoxyethane

Or ethylene oxide is produced by reacting ethene with oxygen in particular conditions. It is a very reactive substance and is used as part of the manufacture of diols which are used in antifreeze solutions. See Epoxyethane

Carbonyl

carbo.png

Aldehydes and ketones are both carbonyls having the C=O bond. It is possible to test between these using Tollens and Fehlings tests. Acylation mechanism of substituion-elimination to produce acyls. See Carbonyl

Aromatic Compounds

The benzene ring (C6H6) with a cloud of delocalised electrons conferring stability. Nitration of benzene to an amine. Electrophillic attack. The Friedel-Crafts Reactions (alkylation and acylation) to make an electrophile. See Aromatic Compounds

Amines and Amino Acids

amine.png

Amines have functional group N and can be primary, secondary or tertiary. Amines can be made by the nucleophillic substitution of ammonia and amines with haloalkanes. Amino acid structure, the R group and proteins. See Amines and Amino Acids

Alkenes

alken.png

Alkenes are unsaturated, having a double covalent C=C bond. Cracking breaks large hydrocarbons to smaller alkenes can be thermal or catalytic. Electrophillic addition to an alkene of bromide, as in bromine water test. See Alkenes

Alkanes

alkan.png

Alkanes are unsaturated hydrocarbons. Their combustion and the catalytic converter. Chlorination of methane in ultra-violet light: initiation, propagation, termination. Distinguishing between alkenes and alkanes by bromine water. See Alkanes

Alcohols

alcoh.jpg

Alcohols have an C-OH functional group. They can be primary, secondary or tertiary. Ethanol can be manufactured by fermentation (drinks) or from ethene (industrial). Alcohols can be oxidized to an aldehyde then carboxylic acid. See Alcohols
