For example, a chain with just one carbon atom in it (CH 4) is the lightest chain, known as methane.Methane is a gas so light that it floats like helium.As the chains get longer, they get heavier. This is known as complete combustion. Chemistry - Hydrocarbons and Fuels (AQA) In GCSE Science one topic studied is crude oil and other types of fuel. This means you can do bubblepoint calculations for the hydrocarbon phase as if there is no water present as long as you use the total hydrocarbon pressure instead of the system pressure in the calculations. Firstly hydrocarbons are defined as molecules only containing carbon and hydrogen, hence -hydro and -carbons. The configuration of an unsaturated carbons include straight chain, such as alkenes and alkynes, as well as branched chains and aromatic compounds.
