Physical property

Chemical property

Ethanol

It is liquid at room temperature with a pleasant smell.

It evaporates at room temperature.

It is soluble in water.

It does not freeze in winters.

It is a highly inflammable liquid that burns with a blue flame to form carbon dioxide and water.

It reacts with sodium to form sodium ethoxide and Hydrogen gas

On heating ethanol at 443 K with excess conc sulphuricacid ,ethene is formed.

It doesnot react with NaOH.

It oxidize to give ethanoic acid in the presence of alkaline KMnO4

Ethanoic acid

It is liquid at room temperature and has vinegar-like smell.

It does not evaporate at room temperature.

It has sour taste.

When pure ethanoic acid is frozen, it forms colorless ice-like solid so it is called glacial acetic acid.

 

The reaction in which alcohol reacts with a carboxylic acid in the presence of sulphuric acid to form, a sweet-smelling substance known as ester is known as esterification

Reaction with base-

Reaction with carbonates and hydrogen carbonates
