Solution

1 mL of ethanol and 1 mL of glacial acetic acid are taken in a test tube. 3-4 drops of concentrated sulphuric acid are then added to a test tube. The resulting mixture in a water bath is then heated (as shown in the figure) for 5 minutes. After this, the contents are poured in a beaker containing 20 mL water. A sweet-smelling compound (ethyl ethanoalte) will be obtained as the product.

Formation of ester

When ethanoic acid reacts with ethanol in the presence of an acid, ethyl ethanoate is formed. Ethyl ethanoate is an ester and has a sweet smell.

Concept: Ethanol
