What is a Carboxylic Acid?
acids are organic molecules which form
an homologous series with the general formula CnH2nO2.
Carboxylic acids are weak acids which react in the same way
as dilute mineral acids. They are named (like hydrocarbons)
according to the number of carbon atoms in the molecule.
HCOOH, has n=1.
C3H7COOH, has n=4.
CH3COOH, has n=2.
C4H9COOH, has n=5.
C2H5COOH, has n=3.
C5H11COOH, has n=6.
The COOH group is the functional group for carboxylic acids.
Below are links to the structural formulae of carboxylic acids.
Methanoic acid Ethanoic acid
Propanoic acid Butanoic acid
Other examples of carboxylic acids are
1. Aspirin - taken as a pain killer and to prevent blood clots
2. Citric Acid - found in oranges, lemons and some soft drinks
3. Tartaric Acid - used in baking powder for cooking
