  • Organic Chemistry
    • Crude Oil and Hydrocarbons
      • Crude Oil
        • Mostly made of hydrocarbons
          • Hydrocarbons
            • Chemical containing carbon and hydrogen
            • Most are alkenes
              • CnH2n
              • Bromine water -colourless
              • Unsaturated hydrocarbon
              • During combustion
                • Smokier orange yellow flame
                • Incomplete
                • Less energy per mole than alkane
              • Double bonds
                • Can undergo more reactions
        • Made of chemicals

        • salt
        • water
        • carbon dioxide
      • Strong acids completely ionise in water
      • Weak acids partially ionise in water
        • Ethanoic acid is weaker than hydrochloric acid
        • Equilibrium when ethanoic acid partially ionises in water
      • Equilibrium when ethanoic acid partially ionises in water
    • Esters
      • Made of carboxylic acid and alcohol
    • Polymers
      • Monomers - small repeating molecule
      • Polymers - made up of many monomers
      • Additional polymerisation
        • Needs a double bond
        • These bonds broken when monomers repeat and add together
          • Needs a double bond
        • Shorthand formula example
      • Thermo -  softening
        • Chains easy to seperate
        • Weak intermolecular forces
        • When cooling forces pull molecules together
        • Can be remoulded when heated
      • Thermosetting
        • Strong covalent bonds
          • Chains fixed together
        • Burns when heated strongly
        • Can change shape + softness by temperature
      • LDPE
        • Low density side branches
          • Prevents tight packing
        • Weak intermolecular forces

        • Strong structure
        • High melting points
      • Condensation polymerisation
        • Releases molecule as monomers come together
          • Often water

          • Carboxylic acid group
        • Forms a peptide bond between N and C
        • DNA
          • Natural polymer
  • Alkanes
    • CnH2n+2
    • No double bonds
    • Fractional Distillation
      • Fractions that burn well can be used as fuels
      • Other fractions can be used as the starting materials
      • Fractional Distillation Diagram Quiz
    • Properties
      • Viscosity gets higher
        • Thick, sticky fluid
      • Flammability gets lower
    • Saturated
