  • Alkanes, alkenes, alcohols and carboxylic acids
    Different homologous series of organic compounds
  • Polymers
    Naturally occurring and synthetic, can be formed from a variety of monomers
  • Alkenes
    Unsaturated hydrocarbons with a double bond between the carbon atoms
  • Homologous series
    • Have the same general formula
    • Differ by CH2 in molecular formulae
    • Show a gradual variation in physical properties, such as boiling points
    • Have similar chemical properties
  • Alkenes
    • Decene
    • Hexene
  • Decene is an alkene with 10 carbon atoms
  • Hexene is an alkene with 6 carbon atoms
  • The ball and stick models show that the covalent bonds are not really at angles of 90°, as shown in the structures
  • Unsaturated hydrocarbons
    Compounds containing hydrogen and carbon only, with at least one double or triple bond
  • C=C bond
    The functional group in alkenes, responsible for their typical reactions
