- Renewable energy
- Solar
- Wind
- Water
- Tidal
- Hydroelectric
- Non-renewable energy sources will eventually run out; are being used faster than being replenished.

- Hydrocarbons
- Hydrogen
- Carbon
- ALKANES
- Methane
- 1 Carbon
- 4 Hydrogen
- Ethane
- 2 Carbons
- 6 Hydrogen
- CnH2n+2
- Propene
- 3 Carbons
- 8 Carbons
- Butane
- 4 Carbons
- 10 Hydrogen
- MenEatProperButter - acronym for order of alkanes
- Saturated
- No space for anymore molecules
- Methane
- Long chains
- Thick; viscous
- Less Volatile
- High B.P
- More Covalent Bonds
- More intermolecular forces
- Broken when heated because weaker than covalent bonds.
- More intermolecular forces
- More Covalent Bonds
- High M.P
- High B.P
- Less flammable
- Examples
- Diesel
- Lubricating Oil
- Separated from short chains through fractional distillation
- Different B.Ps in Crude Oil.
- Short Chains
- Opposite of long chains
- LPG
- Bottled Gases
- ALKENES
- Alkanes cracked to meet demand for specific fractions, e.g, Petrol.
- Longer chains broken down to short chains
- CRACKING
- Longer chains broken down to short chains
- Have C=C bonds
- Ethene
- 2 Carbons
- 4 Hydrogens
- CnH2n
- Carbon must have max. 4 bounds.
- Bromine Saturation test:
- Ethane + Bromine(Br2)
- Dibromoethane
- Bromine molecules take place in the molecule by replacing the double bond
- Similar products with other halogens
- HALOGENATION
- Dibromoethane
- Colour change from orange to colourless
- Ethane + Bromine(Br2)
- Unsaturated
- Space left for other molecules
- ADDITION REACTIONS
- Alkanes cracked to meet demand for specific fractions, e.g, Petrol.
- POLYMERISATION
- Monomers
- One small molecule
- Must have C=C double bond
- Polymers
- Chain of molecules
- Lots of small molecules(monomers)
- Linked together in process called ADDITION POLYMERISATION
- High pressure
- Initiator
- When unsaturated molecules join together, the double bonds break and monomers simply add to make a polymer
- Linked together in process called ADDITION POLYMERISATION
- Lots of small molecules(monomers)
- Plastics
- Examples
- Poly(ethene)
- Poly(styrene)
- Poly(propene)
- Poly(Vinychloride)
- Poly(Vinylethene)
- Chain of molecules
- CONDENSATION POLYMERISATION
- Requires two different monomers
- Duriing each combination, a small molecule is lost (H2))]]
- Monomers
- Renewable energy
