- Carboxylic acids
- Have the functional group -COOH
- The first four are:
- Propanoic acid
- Ethanoic acid
- Butanoic acid
- Methanoic acid
- The structure is written as CH3COOH
- How do the first four carboxylic acids react:
- With Carbonates
- When a carboxylic acid and a carbonate react a salt, water and carbon dioxide is produced.
- The salts form always end in -anoate
- Methanoic acid will form a methanoate
- For example: If ethanoic acid reacts with sodium carbonate
- It produces sodium ethanoate + water + carbon dioxide
- When dissolved in water
- They dissolve in water to make an acidic solution
- This is because they ionise and release H+ ions.
- The acidic solution is weak
- This is because it doesn't ionise completely
- They have a higher pH than acids of the same concentration
- They dissolve in water to make an acidic solution
- With alcohols
- When carboxylic acids react with alcohols they produce esters
- They have the functional group -COO
- The reaction is usually done with a acid catalyst.
- Such as concentratedsulfuric acid
- The only ester name you need to know is ethyl ethanoate
- For example: If ethanoic acid reacts with Ethanol
- Ethyl Ethanoate and water are produced
- With Carbonates
