    • Crude oil, hydrocarbons and alkanes - AQA

      Crude oil is a finite resource. Petrol and other fuels are produced from it using fractional distillation. Cracking is used to convert long alkanes into shorter, more useful hydrocarbons.

    • More organic chemistry - AQA

      Alkanes, alkenes, alcohols and carboxylic acids are different homologous series of organic compounds. Naturally occurring and synthetic polymers can be formed from a variety of monomers.
