- Alcohols
- Basic info
- General formula Cn H2n+1 OH
- Functional group OH
- Name ends in ol
- Examples
- Methanol CH3OH
- Ethanol C2H5OH
- Propanol C3H7OH
- Butanol C4H9OH
- Reactions
- Complete Combustion
- Alcohol + Oxygen goes to CO2 + H2O
- flammable
- React with sodium to produce hydrogen
- Can be oxidised using oxygen from the air to make a carboxylic acid
- ethanol is oxidised using an oxidising agent to make ethanoic acid
- Incomplete Combustion
- alcohols produce carbon/CO monoxide and water.
- CO is poisonous binds to haemoglobin to prevent oxygen form binding which leads to death.
- Colourless and odurless so hard to detect
- Carbon particulates can be dirty causing respiratory and breathing problems.
- CO is poisonous binds to haemoglobin to prevent oxygen form binding which leads to death.
- alcohols produce carbon/CO monoxide and water.
- Complete Combustion
- Uses
- First four are used as fuels
- Ethanol and methanol used as solvents as they can dissolve things water can't
- Fermentation
- Conditions
- temp of approx 40
- yeast as enzyme
- no air so can respire anaerobically
- converts glucose into ethanol + carbon dioxide using yeast (over arrow)
- Conditions
- Basic info
