Resource summary

2.2.1 Alcohols
1 solubility
1.1 OH on water and alcohol molecules form hydrogen bonds
2 Volatility
2.1 Relatively high boiling & melting points due to hydrogen bonding = low volatility
3 Fermentation
3.1 C6H8O6 --> 2CH3CH2OH + 2CO2
3.2 Low temperatures + No oxygen + yeast
3.3 Max % = 14
4 Hydration of ethene
4.1 ethene + H2O --> ethanol
4.2 steam and acid catalyst
4.3 reversible reaction: only 5% produced each time
5 Uses of Alcohols
5.1 Fuel
5.1.1 10% ethanol + petroleum = higher octane grade + burns more clearly
5.2 Alcoholic Drinks
5.2.1 brewed
5.2.2 Distilled
5.3 Methylated spirits
5.3.1 ethanol + methanol + dye
5.3.2 tax free
5.3.3 solvent
5.3.4 spirit lamps
6 Primary alcohol
6.1 1/no alkyl groups
7 Secondary alcohol
7.1 2 alkyl groups
8 Tertiary alcohol
8.1 3 alkyl groups
9 Combustion
9.1 In excess oxygen to produce CO2 and oxygen
10 Oxidation
10.1 oxidising reagant for primary + secondary alcohols
10.1.1 acidified potassium dichromate
10.1.1.1 will turn from orange to green
10.1.2 sulfuric acid
10.2 Primary & Secondary
10.2.1 acidified potassium dichromate
10.2.1.1 primary = aldehyde
10.2.1.2 secondary = ketones
11 Esterification
11.1 alcohol + carboxylic acid + acid catalyst
11.2 warm the alcohol
11.3 produces an ester + water
12 Dehydration
12.1 Forms an alkene
12.2 heated for 40 minutes
12.3 in the presence of an acid catalyst
12.3.1 phosphoric acid
12.3.2 sulfuric acid
