    Crude oil and natural gas are types of hydrocarbon fuel. Crude oil contains a mixture of hydrocarbon compounds and can be separated into fractions like petrol and diesel using distillation. While crude oil provides important fuels and raw materials for polymers like poly(ethene) and petrochemicals, it is a non-renewable resource since fossil fuels take millions of years to form and are being used at a faster rate than they can be replaced.

    Hydrocarbons and Alkanes

    1. Complete the passage using the words below (words cannot be used
    more than once but not all words are needed):

    poly(ethene) finite hydrocarbon thousands

    distillation natural gas infinite chromatography


    fossil petrol petrochemicals methane
    simple non-renewable renewable used
    millions fractional replaced diesel

    Crude oil and ..................................... are types of ................................. fuel. Both

    contain a mixture of .………….…………….… compounds, although natural gas is mainly

    made of ....................... Because crude oil is a mixture of fluids it can be separated


    using the process of ............................. ...............................

    Crude oil is currently one of the most important resources in the world. Many of

    the fractions obtained from crude oil are important fuels such as .....................

    and .......................... However, crude oil also provides raw materials for making

    polymers such as ........................................... Products that are made from crude oil

    are often referred to as ........................................

    Fossil fuels are formed over ................................... of years and they are not
    being ............................. at the rate they are being .............................., so they will
    run out eventually. Because our supply of fossil fuels is ............................... we
    describe them as being ..................................... resources.

    3. The following hydrocarbons are part of a homologous series called the Alkanes.
    They all burn with oxygen, producing carbon dioxide and water, and releasing
    lots of heat as they do so. Draw the displayed formula for each compound.

    Methane (CH4) Ethane (C2H6)

    Propane (C3H8) Butane (C4H10)
