Alkanes
Formula: Cn H2n+2
n=1 methane CH4
n=2 ethane C2 H6
n=3 propane C3 H8
Saturated Hydrocarbons: contain only single carbon-carbon covalent bonds
Properties:
insolube in water
burn in air
mp and bp increases as molecule sizes increases(attractive forces becomes stronger)
density ...
viscosity(more difficult to pour out) ... (intermolecular forces are stronger)
Alkenes
unsaturated hydrocarbons wth one or more carbon-carbon double bonds.
Formula: CnH2n
n=2 Ethene C2 H4
n=3 Propene C3 H6
