Organic Chemistry

Compounds that contain hydrogen and carbon only

contain a six-membered ring of carbon atoms - benzene ring

consist of of open chained carbon atoms and and closed chains (rings) but do not contain a benzene ring

a group of compounds which havethe same functional group and each successive member differs by a CH₂

[Series of compounds with similar chemical type, showing gradations in their physical properties, having a general formula for its members -each member has a similar method of preparations]

a group of atoms on which the characteristics of a homologous series depend

compounds containing all carbon-carbon single bonds

compounds containing at least one carbon-carbon double carbon or one carbon-carbon triple bond

compounds with the same molecular formula but different structural formulas

process involves heating the crude oil and separating the various mixtures on the basis of their boiling points

Early exploding of the petrol-air mixture ('knocking')

a measure of the tendency of the fuel to resist knocking

the breaking down of long-chain hydrocarbon molecules, using heat and a catalyst to produce shorter chains
