- ALCOHOLS
- Methane, ethane, propane, butane, pentane, hexane, heptane, octane
- Displayed= all bonds shown
- Structural= written out structure (cyclo must be shown in a circle)
- Skeletal= lines showing formation of carbon atoms
- Empirical= simplest ratio of formula
- Molecular= general formula
- If molecules have the same molecular formula but different structures they are structural isomers
- 4. If more than one branch- di, tri, tetra
- 3. Number carbons so you can use the lowest numbers
- 2. Prefix is length of branched chain, keep in alphabetical order
- 1. Name longest chain, chains can go round corners
- 2. Prefix is length of branched chain, keep in alphabetical order
- 3. Number carbons so you can use the lowest numbers

- -O-H is hyroxyl. Ethanol is CH3CH2OH
- Number in middle (propan-1-ol) is the carbon atom to which the OH group is attached
- Primary/ secondary/ tertiary is how many hydrocarbon chains are attached to the C with the OH
- 4. If more than one branch- di, tri, tetra
- Tests on alcohols
- Solubility: the first 3 members of the homologous series are soluble
- Primary alcohols can be oxidised
- More reactive further down homologous series
