Carboxylic acids Flashcards
1
Q
What is a carboxylic acid and how are they formed?
A
- A homologous series of organic compounds
- Functional group -COOH
- They are formed from the oxidation of an alcohol
- The names for all of the carboxylic acids end in -anoic
2
Q
What is the functional group of carboxylic acids?
A
- COOH
3
Q
What is the general formula for carboxylic acids?
A
- CnH2n+1COOH
4
Q
Carboxylic acid + metal carbonate
Propanoic acid + potassium chloride
A
= salt + water + carbon dioxide
= potassium propanoate + water + carbon dioxide
5
Q
What type of acids are carboxylic acids?
A
- Caroxylic acids can dissolve in water to ionise partially
- Therefore, they are weak acids
- Only the hydrogen atom from the COOH functional group ionises, all others are strongly bonded
6
Q
What does butanol ionise to form?
A
- Butanoate ion + hydrogen ion
