simplest organic compounds and are a family of chain hydrocarbons having the general formula C2H2n+2. All of the bonds are single bonds (-C-H-‚ and -C-C-). The chains can be straight or branched. The smaller members (less than 4 carbons) are gases‚ while larger ones (five to seventeen carbons) are liquids. Beyond seventeen carbons the alkanes are waxy solids. Structure: The simplest saturated acyclic hydrocarbon is methane‚ CH4. The other hydrocarbons belonging to this class can be taken as descendents

refineries‚ and used as fuel in combustion engines. It is made of over 250 types of hydrocarbons. Aromatic hydrocarbons like toluene and benzene are used to increase the octane rating of gasoline. Other additives are also added to improve engine performance and reduce the emission of harmful gasses formed as byproducts of the combustion process. Some hydrocarbons found in gasoline like benzene are carcinogenic. These hydrocarbons escape into the air around us while we are refilling petrol at a gas station

[1] Carbon can also bond with itself and hydrogen to form both chains and rings called hydrocarbons. Because the covalent bond between carbon and hydrogen is nonpolar‚ these carbon skeletons are hydrophobic. Functional groups can be added to carbon skeletons to make them more hydrophilic. Differences in the carbon skeleton and attached functional

alkenes. Theory: Fuels made from oil mixtures containing large hydrocarbon molecules are not efficient. They do not flow easily and are difficult to ignite. Crude oil often contains too many large hydrocarbon molecules and not enough small hydrocarbon molecules to meet demand. Cracking allows large hydrocarbon molecules to be broken down into smaller‚ more useful hydrocarbon molecules. Fractions containing large hydrocarbon molecules are vaporized and passed over a hot catalyst. This breaks

It is a combustible thick‚ black liquid hydrocarbon which is formed within the earth crust because of millions of years of decomposition (under high pressures and temperatures) of plant and animal matter (Cleveland‚ 1992).
