Lesson Title: Today we are learning about
How are carboxylic acids and esters made and what do they do?
Remember to check for PROGRESS
Focus on Knowledge, Skills and Understanding
Success Criteria: You will show your learning by...
  1. Students should be able to describe what happens when any of the first four alcohols react with an oxidising agent
  2. Carboxylic acids have the functional group ?COOH.
  3. The first four members of a homologous series of carboxylic acids are methanoic acid, ethanoic acid, propanoic acid and butanoic acid. (WS) Opportunies within investigation of the reactions of carboxylic acids.
  4. The structures of carboxylic acids can be represented in the following forms: CH3COOH or displayed formula
  5. Students should be able to recognise carboxylic acids from their names or from given formulae.
  6. (HT only) explain why carboxylic acids are weak acids in terms of ionisation and pH (see Strong and weak acids
  7. Students should be able to describe what happens when any of the first four carboxylic acids react with carbonates
  8. Students should be able to describe what happens when any of the first four carboxylic acids dissolve in water
  9. Students do not need to know the names of individual carboxylic acids other than methanoic acid, ethanoic acid, propanoic acid and butanoic acid.
  10. Students should be able to describe what happens when any of the first four carboxylic acids react with alcohols.
  11. Students are not expected to write balanced chemical equations for the reactions of carboxylic acids.
  12. Students do not need to know the names of esters other than ethyl ethanoate.

Keywords:
  • Dissolve: when particles of solid become incorporated into a liquid to make a solution. (1)
  • Ionisation: the addition or removal of an electron to create an ion. (1)
  • Equilibrium: a state in which a process and its reverse are occurring at equal rates so that no overall change is taking place. (1)
  • Carboxylic acid: an organic acid containing a carboxyl group. (1)

AFL/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.
