Carboxylic Acids
Akopọ
The sharp taste of vinegar comes from ethanoic acid, the best known member of the carboxylic acids. This family is marked by the -COOH functional group, and although these are weak acids, they show all the familiar acid reactions you already know.
In this lesson you will learn that carboxylic acids form a homologous series with the -COOH group, how ethanoic acid reacts with metals, bases and carbonates as a typical acid, and how it reacts with an alcohol to form a sweet-smelling ester.
Awọn Afojusun
- Describe the reaction of ethanoic acid with: (a) metals (b) bases (c) carbonates including names and formulae of the salts produced.
- [Supplement] Describe the formation of ethanoic acid by the oxidation of ethanol: (a) w ith acidified aqueous potassium manganate(VII) (b) b y bacterial oxidation during vinegar production.
- [Supplement] Describe the reaction of a carboxylic acid with an alcohol using an acid catalyst to form an ester.
