Hydrocarbon. Computer graphic of long-chain hydro- carbon molecules floating in space. Hydrocarbons are compounds whose molecules contain only the elements hydrogen and carbon. Long-chain hydrocarbon molecules consist of a single unit (monomer) repeated many times. Plastics,such as polythene (which is made from the monomer CH2CH2),are sometimes made from long-chain hydrocarbon molecules. In polythene,the long chains are tangled together in a solid but flexible mass,giving polythene its strong,pliable quality | |
