Students should be able to describe what happens when any of the first four alcohols react with an oxidising agent |
|
What happens when alcohols react with oxidising agents? |
|
|
|
Carboxylic acids have the functional group ?COOH. |
|
What is the functional group for carboxylic acids? show the structural formula of an alcohol and oxygen and ask what the product might look like. students should then identified the functional group. |
|
|
|
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. |
|
What are the names of the first four members of a homologous series of carboxylic acids? |
|
|
|
The structures of carboxylic acids can be represented in the following
forms: CH3COOH or displayed formula
|
|
What is the structure of the first four members of a homologous series of carboxylic acids? |
|
|
|
Students should be able to recognise carboxylic acids from their names or from given formulae. |
|
What are the names of the following carboxylic acids?
1. HCOOH
2. CH2COOH
3. C2H5COOH
4. C3H7COOH apply previous learning to identify the names and the structures of the first four carboxylic acids |
|
|
|
(HT only) explain why carboxylic acids are weak acids in terms of ionisation and pH (see Strong and weak acids |
|
(HT only) Why are carboxylic acids weak acids in terms of ionisation and pH? |
|
|
|
Students should be able to describe what happens when any of the first four carboxylic acids react with carbonates |
|
What happens when carboxylic acids react with carbonates? |
|
|
|
Students should be able to describe what happens when any of the first four carboxylic acids dissolve in water |
|
What happens when carboxylic acids dissolve in water? Reactions of carboxylic acids:
1. Testing for pH:
universal indicator or universal indicator paper
2. Dissolve in solution and re test the pH
3. React with a metal carbonate and bubble gas through limewater to show products |
|
|
|
Students do not need to know the names of individual carboxylic acids other than methanoic acid, ethanoic acid, propanoic acid and butanoic acid. |

|
Students are not expected to write balanced chemical equations for the reactions of carboxylic acids. |
|
|
