Organic Chemistry
The study of carbon-containing compounds, which form the basis of life and many materials.
In-depth explanation of Organic Chemistry
Organic chemistry is the branch of chemistry that studies compounds built mainly from carbon, usually combined with hydrogen and often with oxygen, nitrogen, sulfur or the halogens. Carbon forms strong, stable covalent bonds to itself and to many other elements, so it can build an almost unlimited range of molecules, from tiny solvents to giant proteins. The field underlies pharmaceuticals, plastics, fuels, fibres, foods and the chemistry of living cells. Once you understand bonding, structure and functional groups, you can predict how a molecule is likely to react and what product it will give.
Going deeper: Organic Chemistry
Key ideas: Organise the field by functional group, not by individual compound: learn the group, its characteristic reactivity (nucleophilic, electrophilic, acidic, basic), then the few reaction types it undergoes. Use the molecular formula, degree of unsaturation and bond polarity to predict where a reagent will attack. Always draw full structures with lone pairs and charges before proposing a mechanism.
Common mistakes and connections: Students try to memorise hundreds of reactions instead of the handful of patterns (substitution, addition, elimination, oxidation, reduction, rearrangement). Another error is ignoring conditions such as solvent, temperature and base strength, which decide the product. Links to bonding, acid-base theory, stereochemistry and spectroscopy.
Visualization of Organic Chemistry
Methane, the simplest organic molecule: one carbon bonded tetrahedrally to four hydrogens, the pattern underlying all of organic chemistry. The interactive lesson shows this as a live animation or chart.
Worked example and use case
Aspirin, sugar, DNA and polyethylene are all organic compounds.
