Alcohols functional group |
OH |
|
|
Are alcohols saturated or unsaturated? |
Saturated |
|
|
General Formula of Alcohols |
Cn H2n+1 OH |
|
|
Equation for Alcohols |
|
|
|
Uses of Ethanol |
Very poisonous, in actual alcohols very small amounts of distilled ethanol |
|
|
Uses of Methanol |
Used to clean |
|
|
Isomers |
|
|
|
Two ways to make ethanol? |
Catalytic Hydration Fermentation |
|
|
Catalytic Hydration to produce ethanol |
Addition of Steam (H2O) to ethene at high temps in the presence of phosphoric acid catalyst |
|
|
Fermentation of Sugars |
Can produce ethanol through anaerobic respiration by fermentation of sugars |
|
|
Fermentation of Sugars Method |
1. Sugars are dissolved in water 2. Yeast is added 3. Mixture is kept at a warm place 4. Air is kept out of the mixture so anaerobic respiration doesnt occur |
|
|
Uses of Alcohols in General |
Fuels, solvent and alcoholic drinks |
|
|
Fuel |
Alcohol is a clean fuel and often added to petrol |
|
|
Solvent |
Dissolver |
|
|
Three reactions of alcohols |
Combustion Oxidation Reactions with sodium |
|
|
Oxidation |
Mild oxidation --> using oxygen in the air Ethanoic acid --> Vinegar (makes Carboxylic Acid) |
|
|
Reactions with Sodium |
All alcohols react, produce hydrogen and salt and fizz. |
|
|
Reactions with sodium equation |
Alcohol + Sodium --> Sodium Salt + Hydrogen |
|
|
Do they react with water? |
Do not react with water, dissolve in water and water forms hydrogen bonds with alcohols |
