11.1 Homologous series
- A homologous series is a set of compounds with one repeating functional group
Physical Properties of Alkanes
- As chain length increases, so does boiling point, as an increased number of electrons causes stronger Van de Waal forces
- The increase in boiling temperature is rapid at first, but flattens off
11.2 Hydrocarbons
- Compounds containing only Hydrogen and carbon
- Three examples,
- Alkanes, Alkenes, Alkynes
Alkanes
- Alkanes have a CH3 group at each end, and are made up of CH2 groups.
- First five are,
- Methane
- Ethane
- Propane
- Butane
- Pentane
