- Organic Chemistry
- Carboxylic Acids
- Dissolve in water to produce ACIDIC solutions
- React with CARBONATES to produce carbon dioxide
- React with ALCOHOLS in the presence of an acid catalyst and produce ESTERS
- Do not ionise completely when dissolved in water-WEAK ACIDS
- Aqueous solutions of weak acids
- Higher pH value that aqueous solutions of strong acids with the same concentration
- Have the functional group -COOH
- Ethanoic acid is an example, which is the main acid in the aqueous solution-vinegar
- Alcohols
- Functional group -OH
- Methanol, Ethanol and Proponal are the first 3 members of the homologous series of alcohols
- Dissolve in water, to form neutral solutions
- React with sodium to produce hydrogen
- Burn in air
- Used as fuels and solvents. Ethanol= Main alcohol in alcoholic drinks
- Ethanol-->Ethanoic acid
- When it is oxidised by Chemical Oxidising Agents or by Microbial Action
- Esters
- Ethyl ethanoate is ester produced from ethanol+ethanoic acid
- Have functional group -COO-
- Volatile compounds with distinctive smells and used as flavourings and perfumes
- Carboxylic Acids
