Key Questions:

1. What happens when alcohols react with oxidising agents?
   • When alochols react with oxidising agents they form carboxylic acids
2. What is the functional group for carboxylic acids?
   • Carboxylic acids have the functional group COOH.
3. What are the names of the first four members of a homologous series of carboxylic acids?
   • The first four members of a homologous series of carboxylic acids are methanoic acid, ethanoic acid, propanoic acid and butanoic acid
4. What is the structure of the first four members of a homologous series of carboxylic acids?
   • the structure of the first four members of a homologous series of carboxylic acids are: 1. methanoic acid = HCOOH 2. ethanoic acid = CH2COOH 3. propanoic acid = C2H5COOH 4. butanoic acid = C3H7COOH
5. What are the names of the following carboxylic acids? 1. HCOOH 2. CH2COOH 3. C2H5COOH 4. C3H7COOH
   • the structure of the first four members of a homologous series of carboxylic acids are: 1. methanoic acid = HCOOH 2. ethanoic acid = CH2COOH 3. propanoic acid = C2H5COOH 4. butanoic acid = C3H7COOH
6. (HT only) Why are carboxylic acids weak acids in terms of ionisation and pH?
   • Carboxylic acids are weak acids as they exist in an equlibrium so don't ever fully ionise (dissossiate)
7. What happens when carboxylic acids react with carbonates?
   • When carboxylic acids react with carbonates they product carbon dioxide gas
8. What happens when carboxylic acids dissolve in water?
   • When carboxylic acids dissolve in water they produce acidic solutions
9. What happens when carboxylic acids react with alcohols?
   • When carboxylic acids react with alochols they produce an ester and water. An acid catalyst is needed.
