Alkanes/Alkenes

Alkanes/Alkenes

1. Alkanes

   • Contain only single bonds.
   • All end in 'ane'.
   • Flammable
   • Can be used as fuel
   • General formula - CNH2N+2
   • Number of Hydrogen atoms = 2x the number of Carbon atoms + 2
   • Methane = CH4
     • Ethane = C2H6
       • Propane = C3H8
         • Butane = C4H10

2. Alkenes

   • General formula - CNH2N
   • A family of compounds that all have the same feature but have different numbers of carbon atoms is called a homologous series.
   • Alkenes all contain a double bond.
   • All end in 'ene'.
   • Flammable
   • Can be used as fuel
   • Number of Hydrogen atoms = 2x the number of Carbon atoms
