 Properties of Derivatives of Hydrocarbons-

2. Carboxylic acid (Example-Ethanoic acid)-

 Physical Properties of Ethanoic acid-

 Ethanoic acid is commonly called acetic acid and belongs to a group of acids
called carboxylic acids.

 Ethanoic acid is a liquid at room temperature.

 Ethanoic acid is soluble in water in all proportions.
5-8% solution of acetic acid in water is called vinegar and is used widely as a
preservative in pickles.

 Ethanoic acidhas a low melting point.
The melting point of pure ethanoic acid is 290 K and hence it often freezes
during winter in cold climates.
This is why, it’s commonly known asglacial acetic acid.

 Carboxylic acids are weak acids.

 Chemical Properties of Ethanoic acid—

As Ethanoic acid is an acid, it shows all the properties of a regular acid.
