Key Topics to Revise

1

1. Hydrocarbons: Alkanes, Alkenes and Alkynes

  • Hydrocarbons are compounds made of only carbon and hydrogen.
  • Alkanes are saturated hydrocarbons and are also called paraffins.
  • Alkanes follow the general formula CnH2n+2.
2

2. Methane and Ethane

  • Methane is the first member of the alkane series.
  • Methane is also called marsh gas.
  • Coal miners call methane fire damp because it forms an explosive mixture with air.
3

3. Ethene: Preparation, Properties and Reactions

  • Ethene is the first member of the alkene series because methylene does not exist in stable form.
  • Ethene is also called ethylene.
  • Ethene is present in small amounts in natural gas and coal gas.
