- Organic compounds
- Alcohols
- Uses
- Alcoholic drinks
- Solvents (dissolve chemicals) - aftershave, perfume, removing ink
- Fuels. Biofuels (ethanol - fermentation or ethene and steam)
- CO2+H2O products
- Alcohols are a group/family of organic chemicals. All contain the functional group -OH (hydroxyl). Homologous series.
- Methanol CH3OH
- Ethanol CH3CH2OH
- Oxidises to form ethanoic acid which is the main acid in vinegar.
- By microbes or chemicals
- Oxidises to form ethanoic acid which is the main acid in vinegar.
- Propanol CH3CH2CH2OH
- Properties
- Burn in air
- React with sodium to produce hydrogen
- Dissolve in water to produce neutral solution
- Uses
- Carboxylic acids
- Functional group -COOH
- Methanoic acid HCOOH
- Ethanoic acid CH3COOH
- Propanoic acid CH3CH2CH2COOH
- Weak acid as the reaction in water is reversible and only some ionize, lower concentration of H+ ions.
- Aqueous solutions have a higher pH than other aqueous solutions of acids with the same concentration
- React with alcohols to create esters
- React with carbonates to produce carbon dioxide
- Dissolve in water to produce acidic solutions
- Esters
- Functional group -COO-
- Smell & taste fruity (can be used for food flavourings
- Are volatile, easily evaporate
- Alcohols
